مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَىٰ
Your Lord did not abandon you and did not turn away in displeasure. (الضحى: 3)
The opening two verses state the objects of oath; verse three supplies the oath response. Beginning with mā negates the feared suggestion that the Prophet ﷺ had been abandoned. The oath gives solemn weight to the reassurance without converting a declarative sentence into a request or command.
In waddʿaka, rabbuka is the subject and -ka the object. The coordinated wa-mā qalā adds a second negative assertion. Together they dispel two aspects of the same concern: abandonment and displeasure. The relationship is stronger than a merely accidental pairing of clauses.
