Abu Musa came to visit Hasan bin Ali during his illness, and Ali said to him, "Have you come as a visitor, or as one gloating?"Abu Musa replied, "Rather, as a visitor."Ali
said to him, "If you have come as a visitor, then I heard the Messenger of Allah ﷺ say, 'When a man visits his Muslim brother, he walks among the harvest of Paradise until he sits down, and when he sits, mercy envelops him. If it is in the morning, seventy thousand angels send blessings upon him until evening, and if it is in the evening, seventy thousand angels send blessings upon him until morning.'"
حدثنا أبو معاوية حدثنا الأعمش عن الحكم بن عتيبة
جاء أبو موسى إلى الحسن بن علي يعوده فقال له علي رضي الله عنه أعائدا جئت أم شامتا قال لا بل عائدا قال فقال له علي رضي الله عنه إن كنت جئت عائدا فإني سمعت رسول الله ﷺ يقول إذا عاد الرجل أخاه المسلم مشى في خرافة الجنة حتى يجلس فإذا جلس غمرته الرحمة فإن كان غدوة صلى عليه سبعون ألف ملك حتى يمسي وإن كان مساء صلى عليه سبعون ألف ملك حتى يصبح
Its isnad is sahih. Abdul-Rahman bin Abu Layla heard from Ali, as Ibn Main said. The hadith was also narrated by Abu Dawud, Tirmidhi, Ibn Majah, Ibn Hibban, and Hakim. See Targheeb wal-Tarheeb 4:162-163. See also 702, 754. "Khurafat al-Jannah," with a kasrah on the kha, Munziri said it means gathering the fruit of Paradise.
