Ali 'Imran 3:160

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

In yanṣur'kumu l-lahu falā ghāliba lakum wa-in yakhdhul'kum faman dhā alladhī yanṣurukum min baʿdihi waʿalā l-lahi falyatawakkali l-mu'minūna

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.
