Azami 1683

Bukhari narrated it in the chapter on wudu (202), from Asbagh bin Faraj Masri, from Ibn Wahb, who said, Amr told me, Abu Nadr told me, from Abu Salama bin Abdul-Rahman, from Abdullah bin Umar, from Saad bin Waqqas. He then related the hadith.In it there is evidence that Umar bin Khattab used to accept the report of a single narrator, and what has been transmitted from him about hesitating to accept such reports only occurred when some doubt arose for him in particular cases. It also shows that levels of trustworthiness vary, and that giving preference between them comes into play when reports conflict. It also shows great honor that Umar showed toward Saad. It also shows that a companion who had accompanied the Prophet for a long time might still be unaware of some clear matters of the sacred law that others come to know, since Ibn Umar denied the permissibility of wiping over the leather socks despite his long companionship and his extensive transmission of hadith.Malik narrated in the chapter on purification (42), from Nafi and Abdullah bin Dinar, that both of them informed him that Abdullah bin Umar came to Kufa to visit Saad bin Abu Waqqas, who was its governor at the time. Abdullah bin Umar saw him wiping over his leather socks and objected to this. Saad said to him, "Ask your father when you return to him." So Abdullah returned, but he forgot to ask Umar about it, until Saad arrived and asked, "Did you ask your father?" He said, "No." So Abdullah asked him, and Umar said, "If you put your feet into the leather socks while they are pure, then wipe over them." Abdullah said, "Even if one of us has just relieved himself?" Umar said, "Yes, even if one of you has just relieved himself."Ahmad likewise narrated it (236), from Abdul-Razzaq, from Ubaydullah bin Umar, from Nafi, from Ibn Umar. Nafi said, "After that, Ibn Umar would wipe over the leather socks as long as he had not taken them off, and he did not set any fixed time limit for doing so."For more, see Fath al-Bari (1/306).
