O my nephew, my people have come to me and said such-and-such. So be merciful to yourself and be merciful to me: do not place me in a situation I cannot bear.
The Quraysh had come to Abu Talib demanding that he either stop the Prophet ﷺ from preaching or hand him over to them to do as they pleased.
Do you see the sun, O my uncle? Wallahi, I have no more power to stop preaching than you do to light your stick with this sun.
Do what you will, my nephew. Fa wallahi, I will never come to you again to stop you. You have my protection.
