Mastering The key beliefs, practices and features of the early Muslim community founded by the Prophet: The nature of belief in Allah to Akhirah: Edexcel IGCSE Islamic Studies Study Notes

Section B of the Edexcel IGCSE (4IS1) Islamic Studies specification moves from biography to theology. These five topics cover what Muslims believe about Allah, prophethood, scripture, predestination and the afterlife, and together they form the doctrinal core of the faith.

This article covers edexcel igcse islamic studies the key beliefs, practices and features of the early muslim community founded by the prophet: the nature of belief in allah to akhirah. For students preparing for the exam, understanding these theological concepts is essential: Section B questions frequently ask you to explain not just what Muslims believe, but why those beliefs matter and how they connect to daily practice. From a comparative perspective, these beliefs show both the continuities Islam shares with other Abrahamic faiths and the theological positions that are distinctively Islamic.

The nature of belief in Allah

The foundational belief in Islam is Tawhid: the absolute oneness of Allah. This is not merely the assertion that there is one God. Tawhid means that Allah alone is worthy of worship, that He has no partners, no equals, and no intermediaries. Every other belief in Islam derives from this principle.

The attributes of Allah. The Qur'an describes Allah through numerous attributes (sifat). The specification highlights three: omnipotence (al-Qadir), Allah as creator (al-Khaliq), and Allah as merciful and just (ar-Rahman, al-Adl). These attributes are not independent qualities but expressions of the same unified divine nature. Allah's mercy does not contradict His justice, and His power does not override His wisdom. Muslim theologians have long emphasised that the attributes must be understood as they are, without reducing them to human analogies (a principle known as bila kayf, "without asking how").

The 99 Names of Allah. The Qur'an contains numerous names and descriptions of Allah, traditionally counted as 99. These names (al-Asma al-Husna) include ar-Rahman (the Most Merciful), al-Alim (the All-Knowing), al-Hakam (the Judge), and as-Sabur (the Patient). Muslims recite and reflect on these names as a form of worship and as a way of understanding the nature of the divine.

Shirk and nifaq. Shirk (associating partners with Allah) is the gravest sin in Islam. It encompasses idol worship, attributing divine qualities to any created being, and placing anything above Allah in one's loyalty and devotion. The Qur'an states that shirk is the one sin that Allah will not forgive if the person dies without repenting (Surah An-Nisa 4:48). Nifaq (hypocrisy) refers to outwardly professing Islam while inwardly disbelieving. The Qur'an devotes considerable attention to the munafiqun (hypocrites) in Madinah who undermined the Muslim community from within.

Exam note: Questions on Tawhid often ask candidates to explain both the concept and its importance. A complete answer should address what Tawhid means, how it is expressed in the Shahadah, why shirk is considered the opposite of Tawhid, and how Tawhid shapes Muslim worship (for example, the prohibition on images in mosques and the direction of all prayer to Allah alone).

Risalah

Risalah (prophethood) is the belief that Allah has communicated with humanity through a series of prophets, each carrying the same essential message: worship Allah alone and live righteously.

The nature of prophethood. Prophets in Islam are human beings chosen by Allah to receive and transmit divine guidance. They are not divine themselves, and they do not share in Allah's attributes. Their role is to serve as models of righteous living and to warn their communities against disobedience and idolatry. Muslims believe that every nation has received a prophet (Surah Fatir 35:24).

Prophets before Muhammad. The specification names six prophets whose stories students must know:

Prophet	Key teachings and events
Adam	The first human and the first prophet. Created from clay by Allah. Placed in the Garden, disobeyed by eating from the forbidden tree, repented and was forgiven. Teaches that humans are fallible but that repentance is always possible.
Ibrahim (Abraham)	Rejected the idolatry of his father and community. Built the Ka'bah with his son Isma'il. Willing to sacrifice his son in obedience to Allah (commemorated in Eid al-Adha). A model of absolute submission (the word "Islam" derives from the same root).
Isma'il (Ishmael)	Son of Ibrahim. Consented to being sacrificed. Helped build the Ka'bah. The ancestor of the Prophet Muhammad through the Arab lineage.
Musa (Moses)	Led the Israelites out of slavery in Egypt. Received the Tawrat (Torah) on Mount Sinai. Confronted Pharaoh. His story is the most frequently mentioned in the Qur'an and illustrates the struggle between truth and tyranny.
Dawud (David)	King and prophet. Received the Zabur (Psalms). Known for his wisdom in governance and his devotion in worship.
Isa (Jesus)	Born miraculously to Maryam (Mary). Performed miracles by Allah's permission. Received the Injil (Gospel). Muslims believe he was not crucified but was raised to heaven by Allah, and that he will return before the Day of Judgment. Islam affirms his prophethood but rejects the Christian doctrines of incarnation and Trinity.

The connection between these prophets is essential: they all preached Tawhid, and their messages were progressively completed by the revelation given to Muhammad as the Seal of the Prophets.

The holy books of Islam

Islam recognises four major revealed scriptures alongside the Scrolls of Ibrahim (Abraham).

Tawrat (Torah) - revealed to Musa. Muslims believe the original Tawrat contained the same monotheistic message as the Qur'an, but that the text was altered over time (a concept known as tahrif).
Zabur (Psalms) - revealed to Dawud. Primarily hymns of praise and wisdom.
Injil (Gospel) - revealed to Isa. Muslims distinguish between the original revelation given to Isa and the existing Christian Gospels, which they consider to contain human additions.
Scrolls of Ibrahim (Abraham) - early revelations, now lost. Referenced in the Qur'an (Surah Al-A'la 87:18-19).
Qur'an - the final and complete revelation, given to Muhammad over 23 years. Muslims believe the Qur'an is the unaltered word of Allah, preserved exactly as it was revealed, and that it supersedes all previous scriptures.

The importance of the holy books for the establishment of Islam lies in continuity. By recognising the earlier scriptures, Islam positions itself not as a new religion but as the restoration and completion of the original monotheistic faith preached by every prophet from Adam onwards.

al-Qadr

Al-Qadr (predestination or divine decree) is the belief that Allah has knowledge of all things and that everything that happens occurs according to His will.

Predestination and free will. This is one of the most intellectually challenging areas of the specification. Muslims believe that Allah's knowledge encompasses everything that has happened and everything that will happen. At the same time, Islamic theology holds that humans possess free will (ikhtiyar) and are responsible for their choices. The reconciliation of these two positions has been debated by Muslim scholars for centuries. The mainstream Sunni position (associated with the Ash'ari school) holds that Allah creates all actions but that humans "acquire" (kasb) moral responsibility for the choices they make.

al-Qadr and the Day of Judgment. Belief in predestination connects directly to belief in judgment. If humans had no genuine choice, then judgment would be unjust. Islamic theology maintains that the balance between divine decree and human responsibility is precisely what makes the Day of Judgment meaningful: people are judged on the choices they freely made, even though Allah knew in advance what those choices would be.

Significance for the early community. Belief in al-Qadr gave the early Muslims resilience in the face of persecution, battle and hardship. The conviction that everything happens by Allah's decree encouraged perseverance (sabr) and trust in Allah (tawakkul), which were essential qualities for a community that faced overwhelming opposition during its formative years.

Evil and suffering. The specification requires students to understand how Muslims approach the problem of evil. Islamic theology holds that suffering can be a test (ibtila), a punishment, or a means of spiritual purification. It does not disprove Allah's existence or goodness, because human understanding is limited while Allah's wisdom is infinite. The Qur'an addresses this directly: "Do people think they will be left alone because they say 'We believe' and will not be tested?" (Surah Al-Ankabut 29:2).

Akhirah

Akhirah (the afterlife) is a central belief in Islam, and the specification covers its key components.

Life after death. Muslims believe that physical death is not the end of existence. The soul continues in a state called Barzakh (the barrier or interval between death and resurrection). During Barzakh, the deceased undergoes questioning by the angels Munkar and Nakir about their faith and deeds.

The Day of Judgment (Yawm al-Qiyamah). At a time known only to Allah, the angel Israfil will blow the trumpet (Sur), the dead will be resurrected, and all people will stand before Allah for judgment. Their deeds will be weighed on the Mizan (scales of justice), and each person will receive their book of deeds in their right hand (indicating salvation) or their left hand (indicating punishment).

Jannah and Jahannam. Jannah (paradise) is described in the Qur'an as gardens beneath which rivers flow, a place of eternal peace, beauty and closeness to Allah. Jahannam (hell) is described as a place of fire and punishment for those who rejected faith and committed evil. The Qur'an's descriptions are vivid and detailed, and the specification expects candidates to be familiar with the key Qur'anic imagery.

Qur'anic expression. The afterlife is one of the most frequently discussed topics in the Qur'an. Surah Al-Qari'ah (101) describes the Day of Judgment and the weighing of deeds. Surah Ar-Rahman (55) describes the rewards of Jannah. Surah Al-Mulk (67) warns of the consequences of disbelief. A strong exam answer will reference specific surahs when discussing Akhirah.

Self-check questions

Explain the concept of Tawhid and why shirk is considered the gravest sin in Islam.
Name three prophets before Muhammad and explain what their stories teach Muslims about the nature of prophethood.
How do Muslims reconcile belief in al-Qadr with belief in human free will?
Describe what happens to the soul between death and the Day of Judgment according to Islamic teaching.
Why is belief in Akhirah important for Muslim daily life and moral behaviour?

These edexcel igcse islamic studies revision notes cover the first half of Section B. The theological depth of these topics means that surface-level answers will not earn high marks. The exam rewards candidates who can articulate the internal logic of Islamic beliefs: how Tawhid connects to Risalah, how Risalah connects to scripture, how scripture connects to al-Qadr, and how all of these converge on the reality of Akhirah.
