Abu Talib ibn ‘Abd al-Muttalib held significant power in Mecca as the head of the Banu Hashim, and this protection made it impossible to have Muhammad silenced or subjected to the kind of torture meted out against the Muslims without protection. The polytheist Meccan leaders approached Abu Talib again and insisted he put a stop to his nephew, Muhammad's preaching of monotheism (Arabic: tawhid), warning that otherwise he would be faced with severe hostility.
Their enmity and open threats of a breach between Abu Talib's clan, the Banu Hashim and the rest of the Banu Quraish distressed Abu Talib who was aware of the cost that his nephew Muhammad had to pay if deserted . Abu Talib sent for Muhammad and told him the news, "Spare me and yourself and put not burden on me that I can’t bear". Muhammad thought that his uncle would let him down and would no longer support him, so he replied: "O my uncle! by God if they put the sun in my right hand and the moon in my left on condition that I abandon this course, until God has made me victorious, or I perish therein, I would not abandon it." Muhammad got up, and as he turned away, his uncle called back and then said "Go and preach what you please, for by God I will never forsake you.". Abu Talib then recited two lines of verse with meanings of full support to Muhammad
