Sunan Ibn Majah 599

Abu Bakr ibn Abi Shaybah reported to us; al-Aswad ibn Amir reported to us; Hammad ibn Salamah reported to us, from Ata ibn al-Saib, from Zadhan, from Ali ibn Abi Talib, from the Prophet (peace and blessings be upon him), who said: ‘Whoever leaves unwashed, in the state of major ritual impurity, a place on his body the size of a hair, such-and-such will be done to him in the Fire.’ Ali said: ‘Because of that, I became hostile to my hair’; and he used to cut it short.
