فينا والله أنزلت: وَنَزَعۡنَا مَا فِي صُدُورِهِم مِّنۡ غِلٍّ إِخۡوَٰنًا عَلَىٰ سُرُرٖ مُّتَقَٰبِلِينَ الحجر: 47
The verse, “And We will remove whatever is in their breasts of resentment, [so they will be] brothers, on thrones facing each other” was, by Allah, revealed about us.
Imam Ahmed and others narrate — from Sufyan — from Isra’il Abu Musa — from Hassan — from ‘Ali.
The narrators of this hadith are all reliable. However, Hassan did not hear (hadith) from ‘Ali.
Ibn Abi Hatim narrates — Muhammad ibn Hammad al Tahrani informed us (in what he wrote to me) — ‘Abdul Razzaq informed us — Ma’mar informed us — from Qatadah that ‘Ali ibn Abi Talib said about the verse, And We will remove whatever is in their breasts of resentment, [so they will be] brothers, on thrones facing each other, “I hope me, Talhah, and Zubair are from those about whom Allah says, ‘And We will remove whatever is in their breasts of resentment…’”
This version of the hadith contains nothing that says it was (specifically) revealed about them (i.e. the family of the Prophet).
 Imam Ahmed: Fada’il al Sahabah, hadith no. 1018.
