﴿ وَتِلْكَ نِعْمَةٌۭ تَمُنُّهَا عَلَىَّ أَنْ عَبَّدتَّ بَنِىٓ إِسْرَٰٓءِيلَ ﴾

“And [as for] that favour of which thou so tauntingly remindest me - [was it not] due to thy having enslaved the children of Israel?””

That is a favour with which you now reproach me that you have enslaved the Children of Israel’ an ‘abbadta banī Isrā’īl is explicative of tilka ‘that’ in other words you have enslaved them but not me there is no favour in that for your enslavement of them is wrong some scholars have reckoned there to be an interrogative hamza of denial at the beginning of this verse a-tilka ni‘matun ‘is that a favour?’.
