Surah Al-Qasas, Verse 35
قَالَ سَنَشُدُّ عَضُدَكَ بِأَخِيكَ وَنَجْعَلُ لَكُمَا سُلْطَٰنًۭا فَلَا يَصِلُونَ إِلَيْكُمَا ۚ بِـَٔايَٰتِنَآ أَنتُمَا وَمَنِ ٱتَّبَعَكُمَا ٱلْغَٰلِبُونَ
Translation — Sahih International
[Allah] said, "We will strengthen your arm through your brother and grant you both supremacy so they will not reach you. [It will be] through Our signs; you and those who follow you will be the predominant."
