مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَىٰ
Your Lord has neither forsaken you nor become displeased.
Mā occurs twice, but with different verbs. The first denies abandonment and the second denies displeasure. The repetition has differentiated content, bringing reassurance on two fronts rather than simply filling the line with duplicated words.
The conjunction wa coordinates the negated claims. By itself it does not prove temporal order or a strict logical dependence between them. Any stronger connection requires contextual argument.
