Abdullah ibn Abbas says when Ameerul Momineen set out for war with the people of Basrah he came to his audience at Dhiqar and saw that he was stitching his shoe. Then Amir al mu'minin said to me, "What is the price of this shoe?" I said: "It has no value now." He then said, "By Allah, it should have been more dear to me than ruling over you but for the fact that I may establish right and ward off wrong." Then he came out and spoke:
Verily, Allah sent Muhammad (S.A.) when none among the Arabs read a book or claimed prophethood. He guided the people till he took them to their (correct) position and their salvation. So their spears (i.e. officers) became straight and their conditions settled down.
By Allah, surely I was in their lead till it took shape with its walls. I did not show weakness or cowardice. My existing march is also like that. I shall certainly pierce the wrong till right comes out of its side. What (cause of conflict) is there between me and the Quraysh? By Allah, I have fought them when they were unbelievers and I shall fight them when they have been misled. I shall be the same for them today as I was for them yesterday.
