Musnad Ahmad 975
It was narrated that ‘Abdullah bin Nafi’ said:
Abu Moosa al-Ash’ari visited al-Hasan bin ‘Ali when he was sick. ‘Ali (رضي الله عنه) said to him: Are you visiting him because he is sick, or is this a social visit? Abu Moosa said: Rather I have come to visit him because he is sick. `Ali (رضي الله عنه) said: I heard the Messenger of Allah (ﷺ) say: “Whoever visits a sick person in the morning, seventy thousand angels will go out with him, all of them praying for forgiveness for him, until evening comes, and he will have a garden in Paradise. And whoever visits a sick person in the evening, seventy thousand angels will go out with him, all of them praying for forgiveness for him until morning comes, and he will have a garden in Paradise.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يَزِيدَ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ عَبْدِ اللَّهِ بْنِ نَافِعٍ، قَالَ عَادَ أَبُو مُوسَى الْأَشْعَرِيُّ الْحَسَنَ بْنَ عَلِيٍّ فَقَالَ لَهُ عَلِيٌّ رَضِيَ اللَّهُ عَنْهُ أَعَائِدًا جِئْتَ أَمْ زَائِرًا فَقَالَ أَبُو مُوسَى بَلْ جِئْتُ عَائِدًا فَقَالَ عَلِيٌّ رَضِيَ اللَّهُ عَنْهُ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَنْ عَادَ مَرِيضًا بَكَرًا شَيَّعَهُ سَبْعُونَ أَلْفَ مَلَكٍ كُلُّهُمْ يَسْتَغْفِرُ لَهُ حَتَّى يُمْسِيَ وَكَانَ لَهُ خَرِيفٌ فِي الْجَنَّةِ وَإِنْ عَادَهُ مَسَاءً شَيَّعَهُ سَبْعُونَ أَلْفَ مَلَكٍ كُلُّهُمْ يَسْتَغْفِرُ لَهُ حَتَّى يُصْبِحَ وَكَانَ لَهُ خَرِيفٌ فِي الْجَنَّةِ‏.‏
