حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا يَحْيَى بْنُ صَالِحٍ، حَدَّثَنَا مُعَاوِيَةُ بْنُ سَلاَّمٍ، حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، عَنْ عِكْرِمَةَ، قَالَ قَالَ ابْنُ عَبَّاسٍ ـ رضى الله عنهما ـ قَدْ أُحْصِرَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَحَلَقَ رَأْسَهُ وَجَامَعَ نِسَاءَهُ، وَنَحَرَ هَدْيَهُ، حَتَّى اعْتَمَرَ عَامًا قَابِلاً.
Allah's Messenger (ﷺ) was prevented from performing (`Umra) Therefore, he shaved his head and had sexual relations with his wives and slaughtered his Hadi and performed Umra in the following year.
