إِن تَسْتَفْتِحُواْ فَقَدْ جَاءكُمُ الْفَتْحُ وَإِن تَنتَهُواْ فَهُوَ خَيْرٌ لَّكُمْ وَإِن تَعُودُواْ نَعُدْ وَلَن تُغْنِيَ عَنكُمْ فِئَتُكُمْ شَيْئًا وَلَوْ كَثُرَتْ وَأَنَّ اللّهَ مَعَ الْمُؤْمِنِينَ
﴿١٩﴾
سورة الأنفال
(8/19) If you ask for a conquest, the conquest has then indeed come to you (to the army that is honorable). And if you desist (from fighting, from opposing), it will be better for you. But if you return (to the war, to denial), We (too) shall return. And your group will be of no avail to you however numerous it be. And verily Allah is with the believers.
Surah Al-Anfal
