Pursue the enemy

And don't be weak in the pursuit of the enemy; if you are suffering (hardships) then surely, they (too) are suffering (hardships) as you are suffering, but you have a hope from Allâh (for the reward, i.e. Paradise) that for which they hope not, and Allâh is Ever All¬Knowing, All¬Wise.

An-Nisa 104

Interior policy and foreign policy

Then what is the matter with you that you are divided into two parties about the hypocrites? Allâh has cast them back (to disbelief) because of what they have earned. Do you want to guide him whom Allâh has made to go astray? And he whom Allâh has made to go astray, you will never find for him any way (of guidance).

They wish that you reject Faith, as they have rejected (Faith), and thus that you all become equal (like one another). So take not Auliyâ' (protectors or friends) from them, till they emigrate in the Way of Allâh (to Muhammad SAW). But if they turn back (from Islâm), take (hold of) them and kill them wherever you find them, and take neither Auliyâ' (protectors or friends) nor helpers from them.

Except those who join a group, between you and whom there is a treaty (of peace), or those who approach you with their breasts restraining from fighting you as well as fighting their own people. Had Allâh willed, indeed He would have given them power over you, and they would have fought you. So if they withdraw from you, and fight not against you, and offer you peace, then Allâh has opened no way for you against them.

You will find others that wish to have security from you and security from their people. Every time they are sent back to temptation, they yield thereto. If they withdraw not from you, nor offer you peace, nor restrain their hands, take (hold of) them and kill them wherever you find them. In their case, We have provided you with a clear warrant against them.

An-Nisa 88-91

Allah prevents from disbelievers

So, fight in the way of Allah. You are not responsible but for yourself, and persuade the believers (to fight in Allah’s way). It is likely that Allah will prevent the mischief of those who disbelieve. Allah is the strongest in power and the mightiest in punishing.

An-Nisa 84

Hypocrites avoid jihad

Have you not seen those who were told to hold back their hands (from fighting) and perform As-Salât (Iqâmat-as-Salât), and give Zakât but when the fighting was ordained for them, behold! a section of them fear men as they fear Allâh or even more. They say: "Our Lord! Why have you ordained for us fighting? Would that You had granted us respite for a short period?" Say: "Short is the enjoyment of this world. The Hereafter is (far) better for him who fears Allâh, and you shall not be dealt with unjustly even equal to a scalish thread in the long slit of a date-stone.

"Wheresoever you may be, death will overtake you even if you are in fortresses built up strong and high!" And if some good reaches them, they say, "This is from Allâh," but if some evil befalls them, they say, "This is from you (O Muhammad SAW)." Say: "All things are from Allâh," so what is wrong with these people that they fail to understand any word?

An-Nisa 77-78

Foreign Policy

What has happened to you that you do not fight in the way of Allah, and for the oppressed among men, women and children who say, “Our Lord, take us out from this town whose people are cruel, and make for us a supporter from Your own, and make for us a helper from Your own.”

The believers fight in the way of Allah, and the disbelievers fight in the way of Taghut. So, fight the friends of Satan. No doubt, the guile of Satan is feeble.

An-Nisa 75-76

Jihad

O you who believe! Take your precautions, and either go forth (on an expedition) in parties, or go forth all together.

There is certainly among you he who would linger behind (from fighting in Allâh's Cause). If a misfortune befalls you, he says, "Indeed Allâh has favoured me in that I was not present among them."

But if a bounty (victory and booty) comes to you from Allâh, he would surely say - as if there had never been ties of affection between you and him - "Oh! I wish I had been with them; then I would have achieved a great success ( a good share of booty)."
Let those (believers) who sell the life of this world for the Hereafter fight in the Cause of Allâh, and whoso fights in the Cause of Allâh, and is killed or gets victory, We shall bestow on him a great reward.
