هَلِ الْأَصْلَحُ لِلْعَبْدِ وَاجِبٌ عَلَى اللَّهِ؟
Is doing what is best for the servant obligatory upon Allah?
Al-aṣlaḥ denotes the more beneficial or more fitting option for a servant. The question is not whether Allah bestows benefits; it concerns a stronger claim of necessity: must Allah, as a matter of rational obligation, invariably choose the most advantageous outcome for each servant?
The Sunni account denies this asserted obligation. That something benefits a servant and that Allah is bound to grant it are different propositions.
