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."
