Sunan Ibn Majah Book 6, Hadith 1442

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنَا الأَعْمَشُ، عَنِ الْحَكَمِ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، عَنْ عَلِيٍّ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ ‏ "‏ مَنْ أَتَى أَخَاهُ الْمُسْلِمَ عَائِدًا مَشَى فِي خِرَافَةِ الْجَنَّةِ حَتَّى يَجْلِسَ فَإِذَا جَلَسَ غَمَرَتْهُ الرَّحْمَةُ فَإِنْ كَانَ غُدْوَةً صَلَّى عَلَيْهِ سَبْعُونَ أَلْفَ مَلَكٍ حَتَّى يُمْسِيَ وَإِنْ كَانَ مَسَاءً صَلَّى عَلَيْهِ سَبْعُونَ أَلْفَ مَلَكٍ حَتَّى يُصْبِحَ ‏"‏ ‏.‏

It was narrated that ‘Ali said:“I heard the Messenger of Allah (ﷺ) say: ‘Whoever comes to his Muslim brother and visits him (when he is sick), he is walking among the harvest 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 blessing upon him until evening, and if it is evening, seventy thousand angels will send blessing upon him until morning.’”
