No Muslim visits a (sick) Muslim early in the morning but seventy thousand angels send blessings upon him
Authentic hadithعن علي رضي الله عنه قال: سمعتُ رسولَ اللهِ صلى الله عليه وسلم يقول: « مَا مِنْ مُسْلِم يَعُودُ مُسْلِماً غُدْوة إِلاَّ صَلَّى عَلَيْهِ سَبْعُونَ ألْفَ مَلَكٍ حَتَّى يُمْسِي، وَإنْ عَادَهُ عَشِيَّةً إِلاَّ صَلَّى عَلَيْهِ سَبْعُونَ ألْفَ مَلَكٍ حَتَّى يُصْبحَ، وَكَانَ لَهُ خَرِيفٌ في الْجَنَّةِ».
‘Ali (may Allah be pleased with him) reported that he heard the Messenger of Allah (may Allah's peace and blessings be upon him) saying: "No Muslim visits a (sick) Muslim early in the morning but seventy thousand angels send blessings upon him until evening comes, and if he visits him in the evening, seventy thousand angels will send blessings upon him until morning comes, and he will have a share of reaped fruits in Paradise.”
Explanation
This Hadīth proves that when a person visits his sick Muslim brother, it is as if he is in the fruitful gardens of Paradise, and Allah's blessings are numerous. It is proof that visiting the sick is a virtuous deed. If it takes place in the morning, then his reward will be that seventy thousand angels send blessings upon him until evening comes, and if it takes place in the evening, his reward will be that seventy thousand angels send blessings upon him until morning comes.
