قُل لَّن يُصِيبَنَآ إِلَّا مَا كَتَبَ ٱللَّهُ لَنَا هُوَ مَوْلَىٰنَا ۚ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ
Commentary:
The expression, save that which Allah has ordained for us, means that victory as ordained by God will always be attained, however great the intervening difficulties. The words that follow, viz. He is our Protector, support this interpretation and also 58:22 which says, Allah has decreed: Of a certainty I will prevail, and My Messengers.
