Mahmud ibn Labid said, "When Sa'd's eye was gravely wounded in the Battle of the Ditch, they moved him to the house of a woman called Rufayda who used to treat the wounded. When the Prophet, may Allah bless him and grant him peace, passed by him, he would inquire, 'How are you this evening?' and in the morning, 'How are you this morning?' and he would tell him."
