Sahih al-Bukhari, Hadith 4259 ⓘ
Ibn `Abbas added: The Prophet married Maimuna during the `Umrat-al-Qada' (i.e. the `Umra performed in lieu of the `Umra which the Prophet could not perform because the pagans, prevented him to perform that `Umra).
وَزَادَ ابْنُ إِسْحَاقَ حَدَّثَنِي ابْنُ أَبِي نَجِيحٍ، وَأَبَانُ بْنُ صَالِحٍ، عَنْ عَطَاءٍ، وَمُجَاهِدٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ تَزَوَّجَ النَّبِيُّ صلى الله عليه وسلم مَيْمُونَةَ فِي عُمْرَةِ الْقَضَاءِ.
