مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَىٰ
Your Lord has not forsaken you, nor has He become displeased.
Ellipsis concerns an unspoken element licensed or recoverable from grammar and context. Mere non-mention is different: a statement need not explicitly say everything one could imagine about its subject.
