[Machine] The Messenger of Allah, peace be upon him, said: "Whenever a person visits a sick person in the evening, seventy thousand angels go out with him and seek forgiveness for him until morning. He will also have a garden (i.e., a reward) in Paradise. And whoever visits a sick person in the morning, seventy thousand angels go out with him and seek forgiveness for him until evening. He will also have a garden (i.e., a reward) in Paradise." This hadith has a valid chain of narrators according to the conditions set by the two sheikhs (i.e., Bukhari and Muslim), but they did not include it in their collections as a group of narrators did not include it due to the statement of Al-Hakam bin 'Utaybah and Mansur bin Al-Mu'tamir and their narrations from Ibn Abi Layla from Ali. However, I believe in the authenticity of the additional narrator.  

قَالَ رَسُولُ اللَّهِ ﷺ «مَا مِنْ رَجُلٍ يَعُودُ مَرِيضًا مُمْسِيًا إِلَّا خَرَجَ مَعَهُ سَبْعُونَ أَلْفَ مَلَكٍ يَسْتَغْفِرُونَ لَهُ حَتَّى يُصْبِحَ وَكَانَ لَهُ خَرِيفٌ فِي الْجَنَّةِ وَمَنْ أَتَاهُ مُصْبِحًا خَرَجَ مَعَهُ سَبْعُونَ أَلْفَ مَلَكٍ يَسْتَغْفِرُونَ لَهُ حَتَّى يُمْسِيَ وَكَانَ لَهُ خَرِيفٌ فِي الْجَنَّةِ» هَذَا إِسْنَادٌ صَحِيحٌ عَلَى شَرْطِ الشَّيْخَيْنِ وَلَمْ يُخَرِّجَاهُ لِأَنَّ جَمَاعَةً مِنَ الرُّوَاةِ أَوْقَفُوهُ عَنِ الْحَكَمِ بْنِ عُتَيْبَةَ وَمَنْصُورِ بْنِ الْمُعْتَمِرِ عَنِ ابْنِ أَبِي لَيْلَى عَنْ عَلِيٍّ مِنْ حَدِيثِ شُعْبَةَ عَنْهُمَا وَأَنَا عَلَى أَصْلِي فِي الْحُكْمِ لِرَاوِي الزِّيَادَةِ
