Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The one who visits the sick remains occupied in gathering the fruits of Paradise, and when he sits with him, mercy covers him."
Al-Bazzar recorded it. Its chain contains Salih bin Musa al-Talhi, who is da'if (weak); the Imams declared him da'if (weak). Ibn Adi said: He is one of those who do not deliberately lie.
