وَأَعِدُّواْ لَهُم مَّا ٱسۡتَطَعۡتُم مِّن قُوَّةٖ وَمِن رِّبَاطِ ٱلۡخَيۡلِ تُرۡهِبُونَ بِهِۦ عَدُوَّ ٱللَّهِ وَعَدُوَّكُمۡ وَءَاخَرِينَ مِن دُونِهِمۡ لَا تَعۡلَمُونَهُمُ ٱللَّهُ يَعۡلَمُهُمۡۚ وَمَا تُنفِقُواْ مِن شَيۡءٖ فِي سَبِيلِ ٱللَّهِ يُوَفَّ إِلَيۡكُمۡ وَأَنتُمۡ لَا تُظۡلَمُونَ

Wa a'iddoo lahum mastata'tum min quwwatinw wa mirribaatil khaili turhiboona bihee 'aduwwal laahi wa 'aduwwakum wa aakhareena min doonihim laa ta'lamoo nahum Allaahu ya'lamuhum; wa maa tunfiqoo min shai'in fee sabeelil laahi yuwaffa ilaikum wa antum laa tuzlamoon

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 and your enemies, and others besides, whom ye may not know, but whom Allah doth know. Whatever ye shall spend in the cause of Allah, shall be repaid unto you, and ye shall not be treated unjustly.
