"Kabshah bint Ka'b bin Malik - she was (married) with Ibn Abi Qatadah - narrated "That Abu Qatadah visited her, [so she said:] 'So I poured water for him to use for Wudu.' She said: 'A cat came to drink, so he lowered he container until it drank.' Kabshah said: 'So he saw me looking at it and said, "O my niece! Are you surprised at that?" So I said yes. He said: "Indeed Allah's Messenger said 'It is not impure, it is only one of those roam around among you.'"
"Jarir bin Abdullah urinated, then he performed Wudu, wiping over his Khuff. So he was asked, 'You do this?' He replied, 'What prevents me, when I have seen Allah's Messenger doing it?" He [Ibrahim] said "And they were impressed by the narration of Jarir since he accepted Islam after the revelation Sural Al-Ma'idah." [This is the saying of lbrahim, that is, "They were impressed."] [He said:] There are narrations on this topic from Umar, Ali, Hudhaifah, AI-Mughirah, Bilil, Sa'd, Abu Ayyub, Salman, Buraidah, Amr bin Umayyah, Anas, Sahl bin Sa'd, Ya'la bin Murrah, Ubadah bin As-Samit, Usamah bin Shank, Abu Umamah, Jabir, Usamah bin Zaid, and Ibn Ubadah. They call him Ibn Imarah and Ubayy bin Imarah.
"I saw Jarir bin 'Abdullah performing Wudu and he wiped over his Khuff. I asked him about that. He replied, 'I saw 'I saw Allah's Messenger performing Wudu and he wiped over his Khuff.' So I said to him, before Surah AI-Ma'idah (was revealed) or after AI-Ma'idah?' So he replied, 'I did not acceot Islam until after Al-Ma'idah.'" Qutaibah narrated this to us; (saying) Khalid bin Ziyad At-Tirmidhi narrated it to us, from Muqatil bin Hayyan, from Shahr bin Hawshah, from Jarir. He said: Baqiyyah related it from Ibrahim bin Adham from Muqatil bin Hayyan, from Shahr bin Hawshah, from Jarir. This Hadith is explanatory, because some who dislike wiping over the Khuff give the interpretation that the Prophet's wiping over the two Khuff was before the revelation of Sural Al-Ma'idah. But in his Hadlth, Jarir mentions that he saw the Prophet wiping over his Khuff after the revelation of Surat Al-Ma'idah.
'When we were traveling, Allah's Messenger would order us not to remove our Khuff for three days and nights, except for Janabah, but not for defecating, urinating, and sleep."
