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.
Ibn ‘Abbas said that if anyone learns God’s Book and follows its contents, he will be guided by God away from error in this world and be guarded by Him on the day of resurrection from the strictest account. A version renders him as saying that one who models his life on God’s Book will not go astray in this world, or be miserable in the next. Then he recited this verse, “He who follows my guidance will not go astray or be miserable.” 1
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ath-Thumali reported God’s messenger as saying, “No people introduce an innovation without its equivalent being withdrawn from the sunna; so holding firmly to a sunna is better than introducing an innovation.”
