Sayyiduna Sahl bin Sa’d Sa’idi (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said:“Islam began in a strange state and it will soon return to the same state as it began, so glad tidings for the strangers.”The companions asked: O Messenger of Allah! Who are the strangers? He (peace and blessings be upon him) said:“Those who set things right when people become corrupt.”
