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.
Mu'allaq (suspended chain): the early portion of the chain is intentionally omitted in the original text.
The Prophet married Maimuna during the `Umrat-al-Qada’ (i.e. the `Umra performed in lieu of the `Umra which the Prophet (ﷺ) could not perform because the pagans, prevented him to perform that `Umra).
