الانفال — Al-Anfal Ayat 19
اِنْ تَسْتَفْتِحُوْا فَقَدْ جَاۤءَكُمُ الْفَتْحُۚ وَاِنْ تَنْتَهُوْا فَهُوَ خَيْرٌ لَّكُمْۚ وَاِنْ تَعُوْدُوْا نَعُدْۚ وَلَنْ تُغْنِيَ عَنْكُمْ فِئَتُكُمْ شَيْـًٔا وَّلَوْ كَثُرَتْۙ وَاَنَّ اللّٰهَ مَعَ الْمُؤْمِنِيْنَ ࣖ
In tastaftiḥū faqad jā'akumul-fatḥ(u), wa in tantahū fa huwa khairul lakum, wa in ta‘ūdū na‘ud, wa lan tugniya ‘ankum fi'atukum syai'aw wa lau kaṡurat, wa anallāha ma‘al-mu'minīn(a).
"If you [disbelievers] seek the victory - the defeat has come to you. And if you desist [from hostilities], it is best for you; but if you return [to war], We will return, and never will you be availed by your [large] company at all, even if it should increase; and [that is] because Allah is with the believers."
