Surely, those who disbelieve after their believing, then increase in unbelief, their repentance shall not be accepted, and these are they that go astray.

Have you not seen those who assert that they believe in what has been revealed to you and what was revealed before you? They desire to summon one another to the judgment of the Shaitan, though they were commanded to deny him, and the Shaitan desires to lead them astray into a remote error.

O you who believe! believe in Allah and His Messenger and the Book which He has revealed to His Messenger and the Book which He revealed before; and whoever disbelieves in Allah and His angels and His messengers and the last day, he indeed strays off into a remote error.

Has not the account reached you of those before you, of the people of Nuh and Ad and Samood, and those after them? None knows them but Allah. Their messengers come to them with clear arguments, but they thrust their hands into their mouths and said: Surely we deny that with which you are sent, and most surely we are in serious doubt as to that to which you invite us.

Allah has promised to those of you who believe and do good that He will most certainly make them rulers in the earth as He made rulers those before them, and that He will most certainly establish for them their religion which He has chosen for them, and that He will most certainly, after their fear, give them security in exchange; they shall serve Me, not associating aught with Me; and whoever is ungrateful after this, these it is who are the. transgressors.

And they disbelieved in it before, and they utter conjectures with regard to the unseen from a distant place.
