Qur'an 3:160 · Aal-i-Imraan

إِن يَنصُرْكُمُ ٱللَّهُ فَلَا غَالِبَ لَكُمْ ۖ وَإِن يَخْذُلْكُمْ فَمَن ذَا ٱلَّذِى يَنصُرُكُم مِّنۢ بَعْدِهِۦ ۗ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ

(160) If Allāh should aid you, no one can overcome you; but if He should forsake you, who is there that can aid you after Him? And upon Allāh let the believers rely.
