It is narrated from Ibn Abi Mulaykah that Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) said: I said to Sayyiduna Uthman bin Affan (may Allah be pleased with him) that the verse 'And those of you who die and leave behind wives' [Surah al-Baqarah: 240] has been abrogated by the other verse, so why are you writing it, or why are you leaving it (in place)? He said: O son of my brother, I will not change anything of it from its place. And in the narration of Ali (bin al-Madini): Why do you write it when it has been abrogated by the other verse, 'And those of you who die and leave behind wives, they shall wait concerning themselves for four months and ten days' [Surah al-Baqarah: 234]?
Imam al-Bukhari (may Allah have mercy on him) narrated it in his Sahih from Umayyah bin Bistam.
