A tradition from the holy Prophet (S) says that he asked Jabir-ibn-Mat'am whether he wished to have the best companions and the most amount of provisions with him when he was on a journey, and he said he did, then, the Prophet (S) said: "Recite these five Suras,: Kafirun, Nasr, Ikhlas, Falaq and Nas, and begin your recitation with /bismillah-ir-rahman-ir-rahim/.” ^2 In another tradition, Imam Sadiq (as) said: "My father has said that Surah Kafirun is one fourth of the Qur'an, and when he recited it he used to say 'I worship only Allah, I worship only Allah".
“Nor will you worship Whom I worship," 6. “To you be your religion, and to me my religion.” Occasion of the Revelation Islamic narrations denote that this Surah was revealed about some of the pagan chiefs of the Quraish tribe such as 'Walid-ibn-i-Muqayrah', 'As-ibn-i-wa'il,’ Harith-ibn-i-Qays'.’ Umiyyah-ibn-i-Khalaf and so on. They said: "O Muhammad Follow our belief and we will follow yours and we will let you enjoy all our privileges.
For one year you should worship our gods and the next year we will worship your God. If your belief is better, we have enjoyed it with you; and if our belief is better, you have enjoyed it with us". The Prophet (S) said: “I take refuge to Allah that I make no match of anything with Him". They said: "You may touch some of our gods, at least, and take a good omen from them. If you do this, we will confirm you and worship your God". The Prophet (S) said: “I am waiting for the command of my Lord".
At that moment this Surah was revealed. Then, the Messenger of Allah went to the Sacred Mosque. A number of the chiefs of the Quraish were gathered there. He stood on a place above them and recited this Surah, wholly, to them. When they heard the message of the Surah they became completely hopeless of their aim and began hurting him and his followers.
