The Repentance - 9:120 Neither the people of the city nor the Arabs around them should lag behind the Messenger of Allah, nor should they prefer themselves to him. For every thirst, fatigue and hunger they suffer in the way of Allah, every step they take in the way of Allah that will anger the disbelievers, and every success they gain against the enemy will be written down as a credit for them. Allah never loses the reward of those who do good.
A general description of the disbelievers:
The Cave/18:56 We have sent the messengers only as bearers of glad tidings and warners. The disbelievers strive to destroy the truth with falsehood and falsehood. They ridiculed My signs and what they were warned about.
The Cave/18:100 On that Day We present Hell to those disbelievers.
The Cave/18:101 Those whose eyes were veiled against My Message, and they could not listen...

The Forgiver/40:5 Noah´s people denied before them, and many parties after them. Each party tried to neutralize their messengers. They argued with vain and false things to remove the truth. At last I seized them; how is My punishment?

The Family Of Imran/3:71 People of the Book! Why do you confuse right and wrong and knowingly conceal the truth?

The Cow/2:146 Those to whom We have given the Book recognize these truths as they recognize their children, yet a group of them knowingly conceal the truth.

The Family Of Imran/3:187 "Allah had taken a promise from those to whom the Book was given, saying, "You will certainly make it clear to the people and you will not conceal it."But they threw it behind their backs and sold it for a small price. What an evil exchange!"

The Women/4:76 Those who believe fight in the way of Allah. And the disbelievers fight in the way of the transgressors and despots. So fight the friends of Satan; Satan´s plan is weak.
