إِذۡ هَمَّت طَّآئِفَتَانِ مِنكُمۡ أَن تَفۡشَلَا وَٱللَّهُ وَلِيُّهُمَاۗ وَعَلَى ٱللَّهِ فَلۡيَتَوَكَّلِ ٱلۡمُؤۡمِنُونَ ١٢٢
When two parties among you were about to lose courage, but Allāh was their ally; and upon Allāh the believers should rely.
Translation: Saheeh International (English)
Each word's meaning and sound
Remember, O Prophet, what happened to two groups of the believers from Banī Salamah and Banī Ḥārithah, when they became weak and almost withdrew when the hypocrites drew back; but Allah aided them, making them firm in fighting, and turning them away from what they had been on the edge of doing. So, let those who have faith look to Allah alone for support, no matter what may happen to them.
