مسند أحمد

Abu Moosa al-Ash`ari visited al-Hasan bin `Ali (when he was sick). `Ali (رضي الله عنه) came in and said: Have you come to visit him (because he is sick), O Abu Moosa, or is it just a (social) visit? He said: No. O Ameer al-Mu`mineen; rather I have come to visit him (because he is sick), ‘Ali (رضي الله عنه) said: I heard the Messenger of Allah (ﷺ) say: `No Muslim visits his fellow Muslim when he is sick but seventy thousand angels send blessings upon him from morning until evening, and Allah grants him a stream in Paradise.` [The narrator] said: O Ameer al-Mu`mineen, what is a stream? He said: The channel that waters palm trees.
