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)

Imam al-Mahdi

All of them denied the Messengers, therefore My punishment (of climate change and mass extinction etc) was justified. (Q38:14)

Priding themselves on earth, and scheming evil. But evil scheming overwhelms none but its authors. Do they expect anything but the precedent of the ancients? You will never encounter an alternative for sunnatullah. You will never find an alteration in the sunnatullah! (Q35:43)

Then, when the messengers gave up hope of their people and realized that they were being treated as liars, Our victory came to them. We then save whom We wish, and Our punishment cannot be swayed from the wicked people. (Q12:110 Q2:214)
They say, ´What is the matter with this Messenger, that he eats food and walks in the market-place? Why has an (influential people as) angel not been sent down to him so that it can be a warner along with him? Why has treasure not been showered down on him? Why does he not have a garden (career) to give him food?´ The wrongdoers say, ´You are merely following a man who is bewitched.´ See how they make comparative judgements about you. They are misguided and cannot find the way. (Q25:7-9)
We never sent any Messengers before you who did not eat food and walk in the market-place. But We have made some of you a trial for others to see if you will be steadfast [in "They are told, ´Have iman in the way that the people have iman,´ they say, ´What! Are we to have iman in the way that fools have iman?" etc]? Your LordLaw (of Nature) sees/proves everything. (Q25:20)
On that Day, We shall ask Hell, Are you now full? Hell will answer, Are there any more? (Q50:30)
