Yunus 10:84

Waqala moosa ya qawmiin kuntum amantum billahi faAAalayhitawakkaloo in kuntum muslimeen

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]."

And Mūsā said, “My people, if you have believed in Allah, then, in Him place your trust if you are obedient.”
