ذَلِكَ بِأَنَّهُ عَلَى كُلِّ شَيْءٍ قَدِيرٌ
This is because Allah has power over all things.
وَكُلُّ شَيْءٍ إِلَيْهِ فَقِيرٌ
Every thing is in need of Allah.
The apparent difficulty: If Allah is omnipotent and every creature dependent, why use ordinary means?
Resolution: Both means and their effects remain dependent on divine power. A person uses lawful means without treating them as autonomous creators of outcomes. Reliance and proper effort can coexist.
Inference to avoid: Dependence does not demand rejecting lawful means, nor does it justify treating a means as independent.
Application: Seeking appropriate treatment while asking Allah for healing is not contradictory.
