Surat Al Anfal: (59-60)

{وَلاَ يَحْسَبَنَّ الَّذِينَ كَفَرُواْ سَبَقُواْ إِنَّهُمْ لاَ يُعْجِزُونَ} [الأنفال: 59]

59- Disbelievers who were not killed in war should not think that they escaped punishment, nay, they are in the grip of Allah and nothing can fail Him because they subject to His Power.

{وَأَعِدُّواْ لَهُم مَّا اسْتَطَعْتُم مِّن قُوَّةٍ وَمِن رِّبَاطِ الْخَيْلِ تُرْهِبُونَ بِهِ عَدْوَّ اللّهِ وَعَدُوَّكُمْ وَآخَرِينَ مِن دُونِهِمْ لاَ تَعْلَمُونَهُمُ اللّهُ يَعْلَمُهُمْ وَمَا تُنفِقُواْ مِن شَيْءٍ فِي سَبِيلِ اللّهِ يُوَفَّ إِلَيْكُمْ وَأَنتُمْ لاَ تُظْلَمُونَ} [الأنفال: 60]

60- Prepare yourselves well to your enemy with arms, armors, and so on.

Once, the Messenger of Allah (peace be upon him) read the Ayah and said: "And make ready against them all you can of power. Verily, power is shooting, verily power is shooting, verily power is shooting." [Reported by Muslim and others]. Shooting is the powerful weapon that a person can use to protect himself and to affect his enemy because a person may hit the leader of the detachment then soldiers flee. The meaning is shooting with all kinds of weapons: Arrows, bullets, artilleries, bombing…etc.

You should also own horses to use them in wars and equipments which suit modern wars in order to frighten the enemies of Allah who disagree with His Commands and your enemies who are eager to kill you, and to frighten other disbelievers whom you do not know by names but Allah knows them.

The more you spend for the sake of Allah and in Jihad, the more you get reward in full on a day when you will be in a dire need to Allah, and you shall not be oppressed by decreasing your reward.
