Surah Ghafir (The Forgiver) 40 : 20

There are clear indications in the subject matter of this Surah to the conditions in which it was revealed. The disbelievers of Makkah at that time were engaged in two kinds of the activities against the Prophet. First, they were creating suspicion and misgiving in the minds of the people about the teaching of the Qur’an and the message of Islam and about the Prophet himself by starting many disputes and discussions, raising irrelevant objections and bringing ever new accusations so that the Prophet and the believers were sick of trying to answer them. Secondly, they were preparing the ground for putting an end to the Prophet himself. They were devising one plot after another, and on one occasion had even taken the practical steps to execute a plot. There is a hadith on the authority of Abdullah bin Amr bin al-As, saying that, one day when the Prophet was offering his prayers in the precincts of the Ka’bah, suddenly ‘Uqbah bin Abi Mu’ait, rushed forward and putting a piece of cloth round his neck started twisting it so as to strangle him to death. Abu Bakr, who happened to go there in time, pushed him away. Abdullah says that when Abu Bakr was struggling with the man, he was saying words to the effect: “Would you kill a man only because he says: God is my Lord?”
