112. Al-Ikhlas (The Sincerity)
Al-Ikhlāṣ (ِArabic: الْإِخْلَاص, "Sincerity"), also known as Al-Tawḥīd (Arabic: التوحيد, "Monotheism") is the 112th chapter (sūrah) of the Quran. 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!" (unique, referring as here to God). 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."
