How shall Allah guide a people who disbelieved after their believing and (after) they had borne witness that the Messenger was true and clear arguments had come to them; and Allah does not guide the unjust people.

And We will remove whatever of ill-feeling is in their breasts; the rivers shall flow beneath them and they shall say: All praise is due to Allah Who guided us to this, and we would not have found the way had it not been that Allah had guided us; certainly the messengers of our Lord brought the truth; and it shall be cried out to them that this is the garden of which you are made heirs for what you did.

And nothing prevented people from believing when the guidance came to them except that they said: What! has Allah raised up a mortal to be a messenger?
