The Messenger has believed in what was revealed to him from his Lord, and so have the believers.

who believe in the unseen, establish the Salats and expend (in Our way) out of what We have bestowed on them

who believe in the Book We have sent down to you (i.e. the Qur'an) and in the Books sent down before you, and firmly believe in the Hereafter

As for those who have rejected (these things), it is all the same to them whether you warn them or do not warn them: they are not going to believe

Then there are some who say, "We believe in Allah and the Last Day", whereas they do not believe at all

They thus try to deceive Allah and the Believers, but they succeed in deceiving none except themselves and they realize it not

And when it is said to them, "Believe sincerely as the other people have believed", they reply, "Should we believe as fools have believed?" Beware! they themselves are the fools, but they know it not

When they meet those who believe, they say, "We, too, are believers", but when they privily meet their evil geniuses, they say, "Indeed we are with you: we are only mocking at these people

And give good news (O Muhammad), to those who believe in this Book and do good deeds (in accordance with its teachings). For them there will be gardens underneath which canals flow. Their fruits will so resemble the fruits on the Earth that every time they will be provided with fruits, they will say, "Such fruits were provided to us before on the Earth. " And there will be pure spouses for them and therein they will live for ever

Well, Allah is not ashamed to cite the similitude of a gnat or of something even more insignificant than this. As for those who believe, they come to know from the same similitude that it is the Revelation from their Lord; but those who disbelieve, say, "What does Allah mean by such similitudes?" Allah leads astray many and guides many to the right way by the same thing. And He leads astray only those who disobey Allah

Rest assured that whosoever from among the Muslims or the Jews or the Christians or the Sabaeans believes in Allah and the Last Day, and performs good deeds, he will have his reward with his Lord and he will have no cause for fear and grief

O Muslims, do you then expect that these people will accept your invitation and become believers? whereas there have always been among them some who have been hearing the Word of God, understanding it well and then perverting and tampering with it knowingly

Then there are among them some un-lettered people who have no knowledge of the Book but depend upon empty hopes and are guided by mere conjecture and guess-work

Only those people who believe and do good deeds, will be the dwellers of the Garden and live there for ever

And when they come to you as captives, you trade on their ransoms whereas their expulsion itself was unlawful for you. Do you then believe in one part of the Scriptures and disbelieve in the other?
