Let him who believes in Allah and the Last Day .............................. " (Hadith 15 of an-Nawawi). (a) Complete the Hadith. (b) Explain its lessons

(a) Completion of the Hadith (Hadith 15 of an-Nawawi, narrated by Abu Hurayrah, R.A.):

The Prophet (S.A.W.) said: "Let him who believes in Allah and the Last Day speak good or keep silent. And let him who believes in Allah and the Last Day honour his neighbour. And let him who believes in Allah and the Last Day honour his guest." (Reported by al-Bukhari and Muslim)

(b) Lessons of the Hadith:

1. Faith is linked to good conduct: True belief in Allah and the Last Day must show itself in righteous behaviour towards others, not merely in words.
2. Guarding the tongue: A believer either speaks what is good and beneficial or remains silent, avoiding lies, backbiting, abuse and idle talk.
3. Good neighbourliness: Honouring the neighbour, helping him, protecting him from harm and being patient with him, is a sign of faith.
4. Hospitality: Honouring the guest, welcoming and feeding him generously, is part of Islamic manners.
5. Accountability in the Hereafter: Awareness of the Last Day motivates the believer to be careful in speech and dealings.
6. Social harmony: When these teachings are practised, peace, love and unity prevail in the community.
