However, if it pleased Mu'awiya, he could let his men fight it out about the water rather than the matter for which they had come. Mu'awiya consulted his advisers, and al-Walid b. 'Uqba urged him to deprive the enemy of water as they had done with 'Uthman. Al- Walid claimed that 'Uthman had been kept without cold water and food for forty days.[^11] 'Ali did not have to rouse his men into action. After they had been without water for a day and night, al-Ash'ath b.
Qays came to him asking for permission to attack and requesting that 'Ali order Malik b. al-Ashtar to join him with his equestrians. 'Ammar b. Yasir got up and shouted among the people. A great number of men came to him. Then he said, “By God, even if they defeat us and chase us as far as the palm trees of Hajar[^12] again we are right and they are wrong.”[^13] Twelve thousand men volunteered, and they swooped down on Abu al-A'war and his men.

That is soundest for you in your worldly affairs and best for your end.” Mu'awiya, “Shall we allow 'Uthman's blood to be spilled for nothing? No, by God, I shall never do that.”[^16] There was now daily skirmishing until the end of Dhu al-Hijja. At the beginning of Muharram 37 a truce was agreed for the month in the hope that a peaceful settlement might be reached. Again, envoys went back and forth between the two camps. The discussion did not go any better than the previous time.
