Answer of The Prophet (Sall Allaho Alehe Wassallam)
:
The Messenger of Allah saw that Abu Talib was very upset by what had happened and was finding it hard to carry on helping him. He said,
'Uncle, by Allah, if they were to place the sun in my right hand and the moon in
my left hand on condition that I abandon this business, I would still not leave
it until Allah makes it victorious or I die doing it.'
The Messenger of Allah wept, then rose and turned away. Abu Talib called out to him, 'Turn round, nephew!'
The Messenger of Allah returned. Abu Talib told him, 'Nephew go and say whatever you like. By Allah, I will never surrender you to anyone.'
