وَأَصْلُ الْقَدَرِ سِرُّ اللَّهِ تَعَالَى فِي خَلْقِهِ
The root of decree is Allah’s secret concerning His creation.
Allah knows all matters, but human beings cannot encompass every hidden detail of decree. Questions that become an objection against divine judgment rather than a search for obedience lead to fruitless dispute.
Belief in decree does not cancel action. One chooses good, avoids wrong, employs lawful means, and entrusts outcomes to Allah. Unknown decree is not a valid excuse for committing sin.
