٦٠. وَأَعِدُّوا۟ لَهُم مَّا ٱسْتَطَعْتُم مِّن قُوَّةٍ وَمِن رِّبَاطِ ٱلْخَيْلِ تُرْهِبُونَ بِهِۦ عَدُوَّ ٱللَّهِ وَعَدُوَّكُمْ وَءَاخَرِينَ مِن دُونِهِمْ لَا تَعْلَمُونَهُمُ ٱللَّهُ يَعْلَمُهُمْ ۚ وَمَا تُنفِقُوا۟ مِن شَىْءٍ فِى سَبِيلِ ٱللَّهِ يُوَفَّ إِلَيْكُمْ وَأَنتُمْ لَا تُظْلَمُونَ
[60] And to encounter them, provide whatever force and trained ever-ready horses you can afford44 whereby you may strike terror into the enemies of Allah and your enemies as well and others besides them whom you do not know but whom Allah knows. The reward of whatever you expend in the way of Allah shall be repaid to you in full, and you shall not be wronged in any way.
44This means, "You should always keep in readiness the necessary military equipment and an organized standing army so that you may be able to take military action immediately without the least delay, should the enemy attack you suddenly. These precautionary measures should be taken so that there should be no confusion and no hurry to urge you to enlist half-trained and ill-equipped volunteers; nor would there be any fear that the enemy would take you unawares and inflict irreparable losses on you before you could get ready for the defense".
