Sunan an-Nasa'i, 710

It was narrated that 'Aishah said:"Sa'd was wounded on the day of Al-Khandaq [1] when a man of Quraish shot him in the medial arm vein. The Messenger of Allah (ﷺ) pitched a tent (Khaimah) for him in the Masjid so that he could visit him close at hand." [1] Al-Khandaq means the trench. This indicates the battle of the trench which took place during the fifth year after Hijrah

Rapporté par 'Aishah : Sa’d a été blessé le jour d’Al-Khandaq lorsqu’un homme de Quraish lui a tiré une flèche dans la veine du bras. Le Messager d’Allah (ﷺ) a installé une tente pour lui dans la mosquée afin de pouvoir lui rendre visite facilement
