عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: مَا مِنْ مُسْلِمٍ يَعُودُ مُسْلِمًا غُدْوَةً إِلَّا صَلَّى عَلَيْهِ سَبْعُونَ أَلْفَ مَلَكٍ حَتَّى يُصْبِحَ وَكَانَ لَهُ خَرِيفٌ فِي الْجَنَّةِ ". رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُد

Abu Sa'id reported God’s messenger as saying, "When you go in to visit an invalid, express a hope that he will live long. That will not avert anything, but it will comfort him.” Tirmidhl and Ibn Majah transmitted it, and Tirmidhi said this is a gharib tradition.
