Say (O Muhammad): ´My Lord has guided me to a straight path, a well-founded deen, Millat Ibrahim (مِّلَّةَ إِبْرَاهِيمَ), a Hanif. He was not one of the idolaters´ (Q6:161) But as for those who have clear evidence from their Lord (Sunnatullah 30:30); followed up by a witness from Him (Revelation 69:40); and before it the ordain of Musa came as a model and a mercy (Tawba 7:156-157): such people have iman in it (Quran). Any faction which rejects it is promised the Fire. Be in no doubt about it. It is the Truth from your Lord. But most people have no iman (Q11:17)

Historical Evidence

Those who have iman (natural person) and do not mix up their iman (FACT) with any wrongdoing (OPINION), they are the ones who are safe; it is they who are guided.´ This is the argument We gave to Ibrahim against his people. (Quran 6:82-83)

Do not follow blindly what you do not know to be true: ears, eyes, and heart, you will be questioned about all these. (Quran 17:36)
