Sayyiduna Abu Mas’ud (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: A Muslim has four rights over another Muslim: when he invites him, he should accept his invitation; when he sneezes, he should say to him“Yarhamukallah”(may Allah have mercy on you); when he falls ill, he should visit him; and when he passes away, he should attend his funeral prayer.
