Narrated 'Aishah (RA):
On the day of al-Khandaq (battle of the Trench), Sa'd was injured and Allah's Messenger (ﷺ) pitched a tent for him in the mosque to visit him from a close distance. [Agreed upon].
وَعَنْ عَائِشَةَ ‏-رَضِيَ اَللَّهُ عَنْهَا‏- قَالَتْ : { أُصِيبَ سَعْدٌ يَوْمَ اَلْخَنْدَقِ , فَضَرَبَ عَلَيْهِ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-خَيْمَةً فِي اَلْمَسْجِدِ , لِيَعُودَهُ مِنْ قَرِيبٍ } مُتَّفَقٌ عَلَيْهِ .‏ 1
