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-Muʿmineen; rather I have come to visit him (because he is sick), ‘Ali ؓ said: I heard the Messenger of Allah ﷺ say: ʿNo 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.ʿ [The narrator] said: O Ameer al-Muʿmineen, what is a stream? He said: The channel that waters palm trees.  

أحمد:٧٠٢ – حَدَّثَنَا عَبِيدَةُ بْنُ حُمَيْدٍ حَدَّثَنِي ثُوَيْرُ بْنُ أَبِي فَاخِتَةَ عَنْ أَبِيهِ قَالَ عَادَ أَبُو مُوسَى الْأَشْعَرِيُّ الْحَسَنَ بْنَ عَلِيٍّ قَالَ فَدَخَلَ عَلِيٌّ فَقَالَ

أَعَائِدًا جِئْتَ يَا أَبَا مُوسَى أَمْ زَائِرًا؟ فَقَالَ يَا أَمِيرَ الْمُؤْمِنِينَ لَا بَلْ عَائِدًا فَقَالَ عَلِيٌّ فَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَا عَادَ مُسْلِمٌ مُسْلِمًا إِلا صَلَّى عَلَيْهِ سَبْعُونَ أَلْفَ مَلَكٍ مِنْ حِينَ يُصْبِحُ إِلَى أَنْ يُمْسِيَ وَجَعَلَ اللهُ تَعَالَى لَهُ خَرِيفًا فِي الْجَنَّةِ قَالَ فَقُلْنَا يَا أَمِيرَ الْمُؤْمِنِينَ وَمَا الْخَرِيفُ؟ قَالَ السَّاقِيَةُ الَّتِي تَسْقِي النَّخْلَ

His father said: "Ali took me by the hand and said: 'Come with us to pay a visit to Al-Hasan.' So we found that Abu Musa was with him.' Ali - peace be upon him - said: 'O Abu Musa! Did you come to visit (the sick) or merely (stop by to) visit?' He said: 'No, to visit (the sick).' So Ali said: 'I heard the Messenger of Allah saying: "No Muslim visits (the sick) Muslims in the morning, except that sevety-thousand angels, sent Salat upon him until the evening, and he does not visit at night except that seventy thousand angels sent Salat upon him until the morning, and there will be a garden for him in Paradise."
