Abdur Rahman bin Abi Laila says that once Sayyiduna Abu Musa (may Allah be pleased with him) came to visit Sayyiduna Hasan (may Allah be pleased with him) for his illness. Sayyiduna Ali (may Allah be pleased with him) said to him: Have you come with the intention of visiting the sick or to express happiness over his illness? He replied: I have come with the intention of visiting the sick. Sayyiduna Ali (may Allah be pleased with him) said: If you have truly come with the intention of visiting the sick, then I heard the Prophet (peace and blessings be upon him) say: When a person visits his Muslim brother who is ill, he walks in the gardens of Paradise until he sits down. When he sits, Allah’s mercy covers him. Then, if he goes in the morning, seventy thousand angels pray for his forgiveness until the evening, and if he goes in the evening, they pray for him until the morning.
