An-Nahl 16:9

WaAAala Allahi qasdu assabeeliwaminha ja-irun walaw shaa lahadakumajmaAAeen

And upon Allāh is the direction of the [right] way, and among them [i.e., the various paths] are those deviating. And if He willed, He could have guided you all.

Undertaken by Allah is (to show) the right path, while there are some (paths) that are crooked. Had He so willed, He would have led all of you to the right path.
