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)
لَهُ عَلِيٌّ أَجِئْتَ عَائِدًا أَمْ شَامِتًا؟ فَقَالَ بَلْ جِئْتَ عَائِدًا فَقَالَ عَلِيٌّ إِنْ جِئْتَ عَائِدًا فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «مَنْ أَتَى أَخَاهُ عَائِدًا فَهُوَ فِي خُرَافَةِ الْجَنَّةِ فَإِذَا جَلَسَ غَمَرَتْهُ الرَّحْمَةُ وَإِنْ كَانَ غُدْوَةً صَلَّى عَلَيْهِ سَبْعُونَ أَلْفَ مَلَكٍ حَتَّى يُمْسِيَ وَإِنْ كَانَ مُمْسِيًا صَلَّى عَلَيْهِ سَبْعُونَ أَلْفَ مَلَكٍ حَتَّى يُصْبِحَ»
