Al-Ikhlas


The Declaration of God's Unity aka Sincerity aka Monotheism, is the 112th chapter of the Quran.
George Sale's translation in its entirety:
According to Sale, this chapter is held in particular veneration by Muslims, and declared, by Islamic tradition, to be equal in value to a third part of the whole Quran. It is said to have been revealed during the Quraysh Conflict with Muhammad in answer a challenge over the distinguishing attributes of the GOD Mohammed invited them to worship.
Al-Ikhlas is not merely the name of this surah but also the title of its contents, for it deals exclusively with Tawhid. The other surahs of the Quran generally have been designated after a word occurring in them, but in this surah the word Ikhlas has occurred nowhere. It has been given this name in view of its meaning and subject matter.

Exegesis

In the early years of Islam, some surahs of the Quran came to be known by several different names, sometimes varying by region. This surah was among those to receive many different titles. It is a short declaration of tawhid, Allah's absolute oneness, consisting of four ayat. Al-Ikhlas means "the purity" or "the refining".
It is disputed whether this is a Meccan or Medinan sura. The former seems more probable, particularly since it seems to have been alluded to by Bilal of Abyssinia, who, when he was being tortured by his cruel master, is said to have repeated "Ahad, Ahad!". It is reported from Ubayy ibn Ka'b that it was revealed after the polytheists asked "O Muhammad! Tell us the lineage of your Lord."

Q112:1-2 none comparable to God

Surah Al-Ikhlas contains four verses:
112:1. Say: He is Allah, One. 112:2. Allah As-Samad. 112:3. He begets not, nor was He begotten. 112:4. And there is none comparable to Him.
About this, Tafsir Ibn Kathir says:
This word cannot be used for anyone in affirmation except Allah the Mighty and Majestic, because He is perfect in all of His attributes and actions.
