It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) asked the people of Quba': "What is this purification for which you have been singled out in this verse: 'In it are men who love to purify themselves, and Allah loves those who purify themselves'?" They said: "O Messenger of Allah (peace and blessings be upon him)! None of us comes out from relieving himself except that he washes his private part."
This hadith is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) only with this chain, and Abd al-Razzaq (may Allah have mercy on him) is alone in narrating it.
