It is narrated from Hazrat Aisha (may Allah be pleased with her) that on the day of the Trench, the vein in Hazrat Saad's arm was wounded. He was struck by an arrow by a person named Ibn al-Arqah. Aisha (may Allah be pleased with her) says: Then the Messenger of Allah (peace and blessings be upon him) had him moved towards the mosque and a tent was set up for him so that the Messenger of Allah (peace and blessings be upon him) could visit him closely.
