Al-Anfâl 8:60
وَأَعِدُّوا لَهُم مَّا اسْتَطَعْتُم مِّن قُوَّةٍ وَمِن رِّبَاطِ الْخَيْلِ تُرْهِبُونَ بِهِ عَدُوَّ اللَّهِ وَعَدُوَّكُمْ وَآخَرِينَ مِن دُونِهِمْ لَا تَعْلَمُونَهُمُ اللَّهُ يَعْلَمُهُمْ ۚ وَمَا تُنفِقُوا مِن شَيْءٍ فِي سَبِيلِ اللَّهِ يُوَفَّ إِلَيْكُمْ وَأَنتُمْ لَا تُظْلَمُونَ ٦٠
WaaAAiddoo lahum ma istataAAtum min quwwatin wamin ribati alkhayli turhiboona bihi AAaduwwa Allahi waAAaduwwakum waakhareena min doonihim la taAAlamoonahumu Allahu yaAAlamuhum wama tunfiqoo min shayin fee sabeeli Allahi yuwaffa ilaykum waantum la tuthlamoona
Make ready for them whatever force and strings of horses you can, to terrify thereby the enemy of God and your enemy, and others besides them that you know not; God knows them. And whatsoever you expend in the way of God shall be repaid you in full; you will not be wronged. (8:60)
