And when those who disbelieve see you, they do not take you but for one to be scoffed at: Is this he who speaks of your gods? And they are deniers at the mention of the Beneficent God.

Have you not seen those who have become hypocrites? They say to those of their brethren who disbelieve from among the followers of the Book: If you are driven forth, we shall certainly go forth with you, and we will never obey any one concerning you, and if you are fought against, we will certainly help you, and Allah bears witness that they are most surely liars.

Surely those who disbelieve in the reminder when it comes to them, and most surely it is a Mighty Book: / Falsehood shall not come to it from before it nor from behind it; a revelation from the Wise, the Praised One.

And when Our clear communications are recited to them, those who disbelieve say to those who believe: Which of the two parties is best in abiding and best in assembly? / And how many of the generations have We destroyed before them who were better in respect of goods and outward appearance! / Say: As for him who remains in error, the Beneficent God will surely prolong his length of days, until they see what they were threatened with, either the punishment or the hour; then they shall know who is in more evil plight and weaker in forces / And Allah increases in guidance those who go aright; and ever-abiding good works are with your Lord best in recompense and best in yielding fruit.

That is because they believe, then disbelieve, so a seal is set upon their hearts so that they do not understand.

And if those who disbelieve fight with you, they would certainly turn (their) backs, then they would not find any protector or a helper.
