Chapter 112 of the Quran talks about the belief in the "Unity of Allah". This chapter, which is called "Al-Ikhlas", emphasizes the oneness and unity of Allah and the importance of believing in Him as the one and only God. The chapter is short but powerful, and it states that Allah is "One, Eternal, Absolute" and that "there is none like unto Him". It is a reminder for Muslims to have pure faith and worship only Allah, and to reject any form of polytheism or associating partners with Allah. The belief in the Unity of Allah is one of the central tenets of Islam, and it is a cornerstone of the faith.
