It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Before me, whenever Allah sent a prophet to any community, He also appointed disciples and companions for him from among his community who would act upon the prophet’s way (sunnah) and follow his commands. But after them, there would come some unworthy people who would say what they did not do themselves, and would do things that they had not been commanded to do."
