Hadith 477

Narrated Muhammad ibn Yahya ibn Hibban: I asked Ubaydullah ibn Abdullah ibn Umar: "Was Abdullah ibn Umar performing wudu for every prayer, whether he was pure or not, and from whom did he take this practice?" He replied: "Asma' bint Zayd ibn al-Khattab narrated to me that Abdullah ibn Hanzala al-Ghaseel told her that the Messenger of Allah ﷺ was commanded to perform wudu for every prayer, whether pure or impure. When this became difficult for the Messenger of Allah ﷺ, he was commanded to use the siwak at each prayer, and the wudu was lifted from him except for after an event of impurity. Abdullah ibn Umar believed he had the strength to do so, and he continued doing it until he died."
