Surah Al-Anfal, ayah 60

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 ٦٠

Wa a'iddū lahum mastata'tum min quwwatin wamir ribātil-khayli turhibūna bihī 'aduwwallāhi wa'aduwwakum wa ākharīna min dūnihim lā ta'lamūnahumullāhu ya'lamuhum wamā tunfiqū min shay'in fī sabīlillāhi yuwaffa ilaykum wa antum lā tuzlamūn

And prepare against them whatever you are able of power and of steeds of war⁴⁵⁶ by which you may terrify the enemy of Allāh and your enemy and others besides them whom you do not know [but] whom Allāh knows. And whatever you spend in the cause of Allāh will be fully repaid to you, and you will not be wronged.
