When All Doors are Closed

Do you ever wonder why when you're most in need, every door you seek of the creation remains closed? You knock on one, but it's slammed shut. So you go to another. It's also shut. You go from door to door, knocking, pounding on each one, but nothing opens. And even those doors you had once depended on, suddenly shut. Why? Why does that happen?

There is nothing left to call on.
But Allah.

And that's the point.

I bear witness, there is no Ilah. Except Allah.

أَمَّن يُجِيبُ ٱلْمُضْطَرَّ إِذَا دَعَاهُ وَيَكْشِفُ ٱلسُّوٓءَ وَيَجْعَلُكُمْ خُلَفَآءَ ٱلْأَرْضِ ۗ أَءِلَٰهٌ مَّعَ ٱللَّهِ ۚ قَلِيلًا مَّا تَذَكَّرُونَ

Is He [not best] who responds to the desperate one when he calls upon Him and removes evil and makes you inheritors of the earth? Is there a deity with Allah? Little do you remember. (QS 27:62)
