أَتَتْرُكُ وَاجِبَكَ وَأَنْتَ تَعْرِفُهُ؟
Will you abandon your duty although you know it?
In a reproachful exchange, the speaker is not primarily collecting information; the question conveys disapproval of abandoning an acknowledged duty. This is an inkārī interrogative reading. The circumstantial clause wa-anta taʿrifuhu intensifies the reproach by recalling the listener’s knowledge.
In a genuine inquiry about an uncertain future choice, the literal question may remain primary. Communicative setting determines the analysis.
