Yahya related to me from Malik from Yahya ibn Said from Yaqub ibn Khalid al-Makhzumi that Abu Asma, the mawla of Abdullah ibn Jafar, told him that he was with Abdullah ibn Jafar when they set out once from Madina. At as-Suqya they passed by Husayn ibn Ali, who was ill at the time. Abdullah ibn Jafar stayed with him and then, when he feared that he was late (for the hajj) he left, and sent for Ali ibn Abi Talib and Asma bint Umays in Madina, and they came to Husayn. Then Husayn pointed to his head, and Ali told someone to shave his head. Then he sacrificed an animal for him at as-Suqya, killing a camel for him.
Yahya ibn Said added, “Husayn had set out with Uthman ibn Affan on that particular journey to Makka.”
