From Sahih Muslim (Hadith 6554):
Thauban, the freed slave of Allah's Messenger (ﷺ), reported Allah's Messenger (ﷺ) as saying:He who visits the sick is supposed to remain in the fruit garden of Paradise. It was said: Allah's Messenger, what is this Khurfat-ul-jannah? He said: It is a place abounding in fruits
