Opposing his [the Prophet's] command and changing his sunna is misguidance and innovation. It is threatened by Allah with utter bereftness and punishment. Allah says, {"Let those who oppose his command beware of a trial that might strike them or a painful punishment that might befall them,"} (Sura an-nûr 24, verse 63) and {"Whoever splits from the Messenger after the guidance is clear to him and follows other than the path of the believers, We shall entrust him to what he has turned to."} (Sura an-nisâ 4, verse 114)
