Abd al-Rahman bin Abi Layla narrates that Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) came to visit Sayyiduna al-Hasan bin Ali (may Allah be pleased with them both), and Sayyiduna Ali (may Allah be pleased with him) asked him: "Have you come to visit the sick, or have you come to gloat out of enmity?" He said: Rather, I have come to visit the sick. Sayyiduna Ali (may Allah be pleased with him) said: "If you have come to visit the sick, then listen: I heard the Messenger of Allah (peace and blessings be upon him) saying: Whoever goes to visit his brother is among the picked fruits of the gardens of Paradise; when he sits down, mercy covers him; if it is the morning, seventy thousand angels pray for him until the evening, and if it is the evening, seventy thousand angels pray for him until the morning." This hadith is sahih (authentic) on the condition of the two Shaykhs, but they did not record it because of a disagreement concerning al-Hakam bin Utaybah.

Abdullah bin Nafi' narrates that Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) visited Sayyiduna al-Hasan bin Ali (may Allah be pleased with them both) while Sayyiduna Ali (may Allah be pleased with him) was present. Sayyiduna Ali (may Allah be pleased with him) asked: "Have you come to pay a visit, or to visit the sick?" He said: To visit the sick. Sayyiduna Ali (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "There is no Muslim who visits a sick person except that seventy thousand angels go out with him to escort him; if he goes in the morning, they escort him until the evening, and he will have a garden in Paradise; and if he goes in the evening, seventy thousand angels escort him until the morning, and he will have a garden in Paradise." This is of the type I have mentioned more than once: one narration does not constitute a defect ('illah) in the other, because Abu Mu'awiyah is the best in memorisation among the students of al-A'mash, and al-A'mash knew the hadith of al-Hakam better than others.

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever visits a sick person continues wading through mercy (until he arrives) until he sits down, and when he sits down (beside the sick person), he becomes fully immersed in that mercy." This hadith is sahih (authentic) on the condition of Muslim, but the two Shaykhs did not record it.
