Sayyiduna Anas (may Allah be pleased with him) says: I heard the Messenger of Allah (peace and blessings be upon him) saying: "Whoever visits a sick person, he immerses himself in the mercy of Allah, and when he sits with him, mercy covers him." When the Messenger of Allah (peace and blessings be upon him) had finished saying what he wanted to say, I asked: This is for the one who visits the sick, so what is there for the sick person? He (peace and blessings be upon him) replied: "When a person remains ill for three days, he becomes purified from sins just as on the day his mother gave birth to him."

Sayyiduna Abu Musa (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: "When a Muslim man falls ill or sets out on a journey, his good deeds are recorded for him just as he used to do them when he was healthy and residing."

Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) said: "There is no sorrow and worry except the sorrow of religion, and there is no pain except the pain of the eye."

Sayyiduna Abu Musa (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said:“For a sick person, the good deeds that he used to do in good health are written for him during his illness. Similarly, for a traveler, the good deeds that he used to do while at home are written for him during his journey.”
