Ghudaif b. al-Harith ath-Thumali reported God’s messenger as saying, “No people introduce an innovation without its equivalent being withdrawn from the sunna; so holding firmly to a sunna is better than introducing an innovation.”
Narrated Malik b. Anas, in mursal form, reported God’s messenger as saying, “As long as you hold fast to two things which I have left among you, you will not go astray:
Hassan said that no people had produced an innovation in their religion without God removing an equivalent amount from their sunna, then not restoring it to them till the day of resurrection.
Abu Dharr reported God’s messenger as saying, “He who separates himself a handbreadth from the community has cast off the rope of Islam from his neck.”
