The reward for visiting the sick

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever visits a sick person in the evening, seventy thousand angels go out with him, seeking forgiveness for him until the morning, and he will have a garden of picked fruits (kharif) in Paradise. And whoever comes to visit in the morning, seventy thousand angels go out with him, seeking forgiveness for him until the evening, and he will have a garden of picked fruits (kharif) in Paradise."
This chain is sahih (authentic) on the condition of the two Shaykhs, but they did not record it, because a group of narrators reported it as mawquf (a statement of the Companion) from al-Hakam bin Utaybah and Mansur bin al-Mu'tamir, from Ibn Abi Layla, from Sayyiduna Ali (may Allah be pleased with him), which is Shu'bah's narration from the two of them; but I hold to my principle that an addition reported by a trustworthy narrator is to be accepted.

It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) visited me because of a pain in my eye.
This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, but neither of them recorded it in their books, and it has an authentic supporting narration (shahid) also narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him).

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) visited Sayyiduna Zayd bin Arqam (may Allah be pleased with him) because of an inflammation (pain and swelling) of his eye.

It is narrated from Sayyidah A'ishah bint Sa'd (may Allah be pleased with her) that her father, Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him), said: I fell ill in Makkah, and the Messenger of Allah (peace and blessings be upon him) came to visit me. He (peace and blessings be upon him) placed his blessed hand on my forehead, then passed it over my chest and my stomach, and then said: 'Allahumma-shfi Sa'dan wa atmim lahu hijratahu' (O Allah, cure Sa'd and complete his emigration for him).
This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, but neither of them recorded it with these words.
