Abu Moosa came to al-Hasan bin ʿAli to visit him when he was sick. ʿAli ؓ said: Have you come to visit him or to gloat? He said: No. I have come to visit him because he is sick. ʿAli ؓ said to him: Since you have come to visit him because he is sick, I heard the Messenger of Allah ﷺ say: “If a man visits his Muslim brother when he is sick, he is walking amongst the fruits 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 blessings upon him until evening, and if it is evening, seventy thousand angels will send blessings upon him until morning.ʿ (Using translation from Aḥmad 612)
"إذا عادَ الرَّجُلُ أخاهُ المُسْلِمَ مَشَى في خْرافة الجنَّةِ حتى يَجْلسَ فإذا جَلَسَ غَمرتْهُ الرَّحمةُ، فإنْ كان غُدْوةً صلَّى عليه سَبْعُون أَلَفَ مَلَكٍ حتَّى يُمْسى، وإنْ كان مَساءً صلَّى عليه سبعونَ ألْفَ مَلَكٍ حَتَّى يُصْبِحَ".
