«رَبِّ أَرِنِي أَنْظُرْ إِلَيْكَ»
My Lord, show me, so that I may look toward You.
The requested object of the showing is recovered from the ensuing «إليك». The point is not seeing in general, but an addressed request concerning a particular vision. The meaning is therefore specific despite the unexpressed complement.
Evidence for ellipsis can precede or follow the verb. What matters is whether the intended object is identifiable through a textual clue. Thus deletion may serve specificity just as it may sometimes suggest breadth.
