أَغَيْرَ اللَّهِ أَتَّخِذُ وَلِيًّا
Shall I take someone other than Allah as a protector?
Placing ghayra Allāh immediately after hamza gives it focal prominence. The denial specifically concerns choosing a protector besides Allah; it is not an indiscriminate inquiry about protection.
As with taqrīr, the element brought under hamza determines the focus. Translation must identify whether the objection concerns the act itself, the actor or a complement, rather than treating every a-question identically.
