Name
Al-Ikhlas is not merely the name of this Surah but also the title of its contents, for it deals exclusively with Tauhid. 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. Whoever understands it and believes in its teaching, will get rid of shirk (polytheism) completely.

Period of Revelation
Whether it is a Makki or a Madani Surah is disputed, and the difference of opinion has been caused by the traditions which have been related concerning the occasion of its revelation. We give them below ad seriatim:

Hadrat Abdullah bin Masud has reported that the Quraish said to the Holy Prophet (upon whom be be peace): "Tell us of the ancestry of your Lord." Thereupon this Surah was sent down. (Tabarani).

Abul Aliyah has related on the authority of Hadrat Ubayy bin Kab that the polytheists said to the Holy Prophet (upon whom be peace): “Tell us of your Lord's ancestry." Thereupon Allah sent down this Surah. (Musnad Ahmad, Ibn Abi Harim, Ibn Jarir, Tirmidhi, Bukhari in At-Tarikh, Ibn al-Mundhir, Hakim, Baihaqi). Tirmidhi has related a tradition on the same theme from Abul Aliyah, which does not contain any reference to Hadrat Ubayy bin Kab, and has declared it to be more authentic.

Hadrat Jabir bin Abdullah has stated that a bedouin (according to other traditions, some people) said to the Holy Prophet (upon whom be peace): "Tell us of your Lord's ancestry." Thereupon Allah sent down this Surah.(Abu Yala, Ibn Jarir, Ibn al-Mundhir, Tabarani in Al-Ausat, Baihaqi, Abu Nuaim in Al-Hilyah).

Ikrimah has related a tradition form Ibn Abbas, saying that a group of the Jews, including Kab bin Ashraf, Huyayy bin Akhtab and other, came before the Holy Prophet (upon whom be peace) and said: "O Muhammad (upon whom be Allah's peace and blessings), tell us of the attributes of your Lord, who has sent you as a Prophet." Thereupon Allah sent down this Surah. (Ibn Abi Hatim, Ibn Adi, Baihaqi in Al-Asma was-Sifat).

In addition to these, some other traditions also have been cited by Ibn Taimiyyali in his commentary of Surah Al-Ikhlas, which are as follows;

Hadrat Anas has stated that some Jews of Khaiber came before the Holy Prophet (upon whom be peace) and they said: "O Abul Qasim, Allah created the angels from light, Adam from rotten clay, Iblis from the flame of fire, the sky from smoke, and the earth from the foam of water. Now tell us about your Lord (of what He is made)." The Holy Prophet (upon whom be peace) did not give any reply to this question. Then Gabriel came and he said: "O Muhammad, say to them: Huwa Allahu ahad."

Amir bin at-Tufail said to the Holy Prophet: "O Muhammad, what do you call us to?"The Holy Prophet replied: "To Allah." Amir said, "Then, tell us of what He is made, whether of gold, silver, or iron?" Thereupon this surah was sent down.

Dahhak, Qatadah and Muqatil have stated that some Jewish rabbis came before the Holy Prophet, and they said: "O Muhammad, tell us what is your Lord like, so that we may believe in you. Allah in the Torah has sent down His description. Kindly tell us of what He is made, what is His sex, whether He is made of gold, copper, brass, iron, or silver, and whether He eats and drinks. Also tell us from whom He has inherited the world, and who will inherit it after Him." Thereupon Allah sent down this Surah.

Ibn Abbas has reported that a deputation of the Christians of Najran along with seven priests visited the Holy Prophet upon whom be peace), and they said: "O Muhammad, tell us what is your Lord like and of what substance He is made."The Holy Prophet replied, "My Lord is not made from any substance. He is unique and exalted above everything." Thereupon Allah sent down this Surah.
