And whoever acts hostilely to the Messenger after that guidance has become manifest to him, and follows other than the way of the believers, We will turn him to that to which he has (himself) turned and make him enter hell; and it is an evil resort.

And how do they make you a judge and they have the Taurat wherein is Allah's judgment? Yet they turn back after that, and these are not the believers.

And (as for) those who believed afterwards and fled and struggled hard along with you, they are of you; and the possessors of relationships are nearer to each other in the ordinance of Allah; surely Allah knows all things.

And they say: We believe in Allah and in the messenger and we obey; then a party of them turn back after this, and these are not believers.

If you both turn to Allah, then indeed your hearts are already inclined (to this); and if you back up each other against him, then surely Allah it is Who is his Guardian, and Jibreel and -the believers that do good, and the angels after that are the aiders.
