Al-Qasas 28:35

قَالَ سَنَشُدُّ عَضُدَكَ بِأَخِيكَ وَنَجْعَلُ لَكُمَا سُلْطَـٰنًا فَلَا يَصِلُونَ إِلَيْكُمَا ۚ بِـَٔايَـٰتِنَآ أَنتُمَا وَمَنِ ٱتَّبَعَكُمَا ٱلْغَـٰلِبُونَ

Qāla sanashuddu ʿaḍudaka bi-akhīka wanajʿalu lakumā sul'ṭānan falā yaṣilūna ilaykumā biāyātinā antumā wamani ittabaʿakumā l-ghālibūna

[Allāh] 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."
