It is narrated from Sayyiduna Mahmood bin Labeed (may Allah be pleased with him) that on the day of the Battle of the Trench, when Sayyiduna Sa’d (may Allah be pleased with him) had his vein cut and his pain increased greatly, they transferred him to a woman named Rufaidah who used to treat the wounded. Whenever the Prophet (peace and blessings of Allah be upon him) passed by him, he would ask:“How did you spend your evening?”And when inquiring about his condition in the morning, he would ask:“How did you spend your morning?”So he would inform him of his condition.
