VISITING THE SICK H 363 "When someone visits a sick person or a brother for the sake of Allah, he is called by a herald who says: 'You are good and your walking is good and you will enter a residence in Paradise.'" R 363 Tirmidhi with a chain up to Abu Hurairah who related that the Prophet, praise and peace be upon him, said this.
