And not We have made their number except (as) a trial for those who disbelieve - that may be certain those who were given the Scripture and may increase those who believe (in) faith, and not may doubt those who were given the Scripture and the believers, and that may say those in their hearts (is) a disease and the disbelievers "What (does) intend Allah by this example?" Thus does let go astray Allah whom He wills and guides whom He wills. And none knows (the) hosts (of) your Lord except Him. And not it (is) but a reminder to (the) human beings.

32:12
And if you (could) see when the criminals (will) hang their heads before their Lord, "Our Lord we have seen and we have heard, so return us, we will do righteous (deeds). Indeed, we (are now) certain."

And for their saying, "Indeed, we killed the Messiah, Isa, son (of) Maryam, (the) Messenger (of) Allah." And not they killed him and not they crucified him but it was made to appear (so) to them. And indeed, those who differ in it (are) surely in doubt about it. Not for them about it [of] (any) knowledge except (the) following (of) assumption. And not they killed him, certainly.

2:118
And said those who (do) not know, "Why not speaks to us Allah or comes to us a sign?" Like that said those from before them similar their saying. Became alike their hearts. Indeed, We have made clear the signs for people (who) firmly believe.

5:50

2:4
And those who believe in what (is) sent down to you and what was sent down from before you and in the Hereafter they firmly believe.

52:36
Or (did) they create the heavens and the earth? Nay, not they are certain.

45:4
And in your creation and what He disperses of (the) moving creatures (are) Signs for a people who are certain.

45:20
This (is) enlightenment for mankind and guidance and mercy for a people who are certain.
