Surah Yunus, ayah 84

وَقَالَ مُوسَىٰ يَٰقَوۡمِ إِن كُنتُمۡ ءَامَنتُم بِٱللَّهِ فَعَلَيۡهِ تَوَكَّلُوٓاْ إِن كُنتُم مُّسۡلِمِينَ ٨٤

Waqāla mūsā yāqawmi in kuntum āmantum billāhi fa'alayhi tawakkalū in kuntum muslimīn

And Moses said, "O my people, if you have believed in Allāh, then rely upon Him, if you should be Muslims [i.e., submitting to Him]."
