Quran 6: 125:
So whoever Allah wants to guide – He expands his breast to [contain] Islam; and whoever He wants to misguide – He makes his breast tight and constricted as though he were climbing into the sky. Thus does Allah place defilement upon those who do not believe.
The following excerpt is taken from “The Quran with Annotated Interpretation” by Ali Unal pg. 301 note 27:
It is possible to see here a Qur’ānic miracle concerning scientific developments. As we now know, as we ascend a mountain, or go up in the air, the amount of oxygen diminishes, the air pressure decreases, and breathing becomes impossible without special equipment. The Qur’ān describes the state of one who feels depressed in the face of Islam and insists on not believing in it, despite many signs and all the evidence that they see, in the terms of a physical fact, thus alluding to a scientific fact which would be discovered centuries later.
The following excerpt is taken from “Quran English Commentary and Translation” by Abdullah Yusuf Ali pg. 68:
C947. Allah’s Universal Plan is the Qadha wa Qadr, which is so much misunderstood. That Plan is unalterable, and that is His Will. It means that in the spiritual world, as in t physical world, there are laws of justice, mercy, grace, penalty, etc., which work as surely as anything we know. If, then, a man refuses Faith, becomes a rebel, with each step he goes further and further down, and his pace will be accelerated; he will scarcely be able to take spiritual breath, and his recovery -in spite of Allah’s mercy which
he has rejected-will be as difficult as if he had to climb up to the skies.
On the other hand, the godly will find, with each step, the next step easier. Jesus expressed this truth paradoxically: “He that hath, to him shall be given; but he that hath not, from him shall be taken away even that which he hath”: Mark, 4:25. John (6:65) make Jesus say: “No man can come unto me, except it were given unto him of my Father.”
