فَوَيْلٌ لِمَنْ صَارَ لِلَّهِ تَعَالَى فِي الْقَدَرِ خَصِيمًا
Woe to the one who becomes an adversary concerning Allah’s decree.
A person who believes he can penetrate hidden realities through defective conjecture, then disputes Allah’s decision, has not thereby mastered predestination. Such a course risks falsehood and sin. A servant must acknowledge the truth of divine knowledge and avoid groundless contention.
