Fact..
In the comprehensive definition of Allah’s name “Al-Fattāh”, I cited what the scholars said in this regard. But I will pause here with the verse that says:
{Whatever mercy Allah grants to people -none can withhold it; and whatever He withholds -none can release it thereafter. And He is the All-Mighty, the All-Wise.}
[Surat Fātir: 2]
A fact that the believer should always bear in mind is that no one can achieve any desire or fulfill any need except through Allah Almighty, and nothing can happen except according to His will. There is no power nor strength in the entire universe except through Him, and Him alone.
No cell moves, no atom exists, no drop of water evaporates, and no leaf falls off a tree without His permission and will.
The entire world cannot cause you any harm unless Allah Almighty wills, nor can they save you from harm that Allah predestined for you.
One of the righteous predecessors wrote to his brother: “If Allah is with you, then whom would you fear? And if He is against you, then to whom would you turn?”
