"for the Unbelievers are open enemies to you." 4:101
For the Unbelievers, Allah has prepared a humiliating punishment. 4:102
O you who believe! Take not the Jews and the Christians for your friends and protectors: they are but friends and protectors to each other. And he among you that turns to them for friendship is of them. 5:51
Of the Jews:
‘When in their insolence they transgressed all prohibitions, We said to them: "Be you apes, despised and rejected."’ 7:166
"Many are the men We have made for Hell…" 7:179
Remember your Lord inspired the angels with the message: "I am with you: give firmness to the Believers: I will instill terror into the hearts of the Unbelievers: you smite them above their necks and smite all their finger-tips off them." 8:12
Against them make ready your strength to the utmost of your power, including steeds of war, to strike terror into the hearts of the enemies of Allah. Whatever you spend in the cause of Allah shall be repaid to you and you shall not be treated unjustly. 8:60
O Messenger! Rouse the Believers among you to the fight. If there are twenty amongst you, patient and persevering, they will vanquish two hundred: if a hundred, they will vanquish two thousand of the Unbelievers: for these are people without understanding. 8:65
…Then fight and slay the Pagans wherever you find them, seize them, beleaguer them, and lie in wait for them in every stratagem of war…9:5
Fight them and Allah will punish them by your hands, cover them with shame, help you to victory over them, heal the breasts of the Believers. 9:14
Fight those who do not believe in Allah … until they pay the Jizya with willing submission and feel themselves subdued. 9:29
Therefore, when you meet the Unbelievers in fight, smite at their necks; at length, when you have thoroughly subdued them, bind a bond firmly on them… He lets you fight in order to test you, some with others. But those who are slain in the way of Allah, - He will never let their deeds be lost. 47:4
It is He Who got out the Unbelievers among the People of the Book from their homes at the first gathering of the forces. Little did you think that they would get out: and they thought that their fortresses would defend them from Allah! But the wrath of Allah came to them from quarters from which they had little expected it, and cast terror into their hearts, so that they destroyed their own dwellings by their own hands and the hands of the Believers. 59:2
They will not fight you even together, except in fortified townships, or from behind walls. Strong is their fighting spirit amongst themselves: you would think they are united, but their hearts are divided: that is because they are a people devoid of wisdom. 59:14
