According to Ibn 'Abbas, the Prophet (pbuh) said to the people: "Should I tell you the word which will protect you from polytheism? It is that you should recite Qul ya-ayyuhal Kafirun when you go to bed." (Reported by Abu Ya'la, Tabarani). Sayyiduna Khabbab says: "The Holy Prophet (pbuh) said to me 'when you lie down in bed to sleep, recite Qul ya-ayyuhal Kafirun, this was the Prophet's own practice when he lay down to sleep.'" - (Reported by Bazzar, Tabarani, Ibn Marduyah).

Having made it a part of the Qur'an, Allah gave the Muslims the eternal teaching stating that they should exonerate themselves by word and deed from the creed of Kufr, wherever and in whatever form it may be, and that they should declare without any reservation that they cannot make any compromise with the disbelievers in matters of Faith. Although it was initially addressed to the disbelieving Qureysh in response to their proposals of compromise, it is not confined to them only.


This Surah was not revealed to preach religious tolerance as some people of today seem to think, but was revealed in order to exonerate the Muslims from the disbelievers religion, their rites of worship, and their gods to express their total disgust and unconcern with them to tell them that Islam and Kufr (unbelief) had nothing in common and that there was no possibility of their ever being combined and mixed into one entity.
