Sunan Ibn Majah 1442

It was narrated that ‘Ali said:“I heard the Messenger of Allah (ﷺ) say: ‘Whoever comes to his Muslim brother and visits him (when he is sick), he is walking among the harvest of Paradise until he sits down, and when he sits down he is covered with mercy. If it is morning, seventy thousand angels will send blessing upon him until evening, and if it is evening, seventy thousand angels will send blessing upon him until morning.’”
