Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Whoever visits a sick person or a brother of his for Allah's sake, a caller calls out: 'May you be glad, may your footsteps be blessed, and may you dwell a home in Paradise!'"
Anyone who goes to visit a sick person or visits one of his brothers for the sake of Allah, an angel calls out from the heavens and says: "You have been purified of your sins and been made glad for the abundant reward that Allah has for you, and have owned a palace in Paradise to live in."
