The Messenger of Allah ﷺ said to me, "Abdullah, do not be like so-and-so. He used to pray during the night, then he abandoned praying at night."
قال لي رسول الله ﷺ: يا عبد الله، لا تكن مثل فلان كان يقوم من الليل فترك قيام الليل.
Bukhari related it in tahajjud (1152) via the route of Mubashshir and Abdullah bin Mubarak, both from Uzai, who said, "Yahya bin Abu Kathir narrated to us," who said, "Abu Salama bin Abdul-Rahman narrated to me," who said, "Abdullah bin Amr bin As narrated to me," and he mentioned it. Then Bukhari said, "Hisham said, 'Ibn Abu Ishrin narrated to us,' who said, 'Uzai narrated to us,' Yahya said, from Umar bin Hakam bin Thawban, who said, 'Abu Salama narrated the same to me.' And Amr bin Abu Salama followed him, from Abu Salama, from Uzai." End of quote.Ibn Hajar said in Fath al-Bari, "Hisham is Ibn Ammar, and Ibn Abu Ishrin, spelled with the numeral form, is Abdul-Hameed bin Habib, the scribe of Uzai. The author, Bukhari, intended by bringing this suspended report to draw attention to the fact that the addition of Umar bin Hakam, that is, Ibn Thawban, between Yahya and Abu Salama is one of the additions found within otherwise connected chains, because Yahya explicitly stated that he heard directly from Abu Salama, and had there been an intermediary between them, he would not have explicitly stated hearing it directly. The mentioned narration of Hisham was connected by Ismaili and others.""His statement, 'Amr bin Abu Salama followed him,' means that he followed Ibn Abu Ishrin in the addition of Umar bin Hakam. The mentioned narration of Umar was connected by Muslim (in fasting, 185/1159) from Ahmad bin Yunus, from him. The apparent practice of Bukhari gives preference to the narration of Yahya from Abu Salama without an intermediary. The apparent practice of Muslim contradicts this, since he confined himself to the narration with the addition, and the preferred view according to Abu Hatim, Daraqutni, and others is the practice of Bukhari." This ends Ibn Hajar's statement.The practice of Muslim is not to be faulted by the practice of Bukhari, because it appears that Yahya bin Abu Kathir first heard from Umar bin Hakam, from Abu Salama, and this is what came down to Muslim, so he narrated it through that route. Then it became possible for him to hear directly from Abu Salama, so he narrated from him directly, and this is what came down to Bukhari, who narrated through that route and suspended the route with the addition. Thus what is with Bukhari is given preference over what is with Muslim, because of the higher elevation of its chain.
