“So fear Allah as much as you are able.” [al-Taghābun: 16]
And His words:
“And those who believe and do righteous deeds—We do not burden any soul beyond its capacity—” [al-A‘rāf: 42]
And other such passages. Thus, these people who are negligent and overstep the bounds concerning the fundamentals of religion, if they cannot hear what was revealed to the Messenger, fall into this category.
[Their disagreement concerning what is commanded but which Allah knows will not occur]
Likewise, they disagree concerning an act that is commanded but which Allah knows will not occur, or which He has also declared will not occur. Some people say that such an act is beyond one’s capacity, just as the extreme Qadariyyah deny that Allah can know, declare, or record beforehand that it will not occur. This is because both groups agree that the contrary of what is known cannot be possible or within one’s capacity.
The majority, however, disagree with them on this point, saying: “Their position is undermined by Allah’s power, for He has declared His ability to do things that He nevertheless does not do,” as in His words:
“Yes indeed, We are able even to restore his fingertips.” [al-Qiyāmah: 4]
And His words:
“And We are certainly able to take it away.” [al-Mu’minūn: 18]
And His words:
“Say: He is able to send punishment upon you from above you or from beneath your feet.” [al-An‘ām: 65]
He also says:
“Had your Lord willed, He would have made humankind one community.” [Hūd: 18]
And there are similar passages in which He declares that, had He willed something, He would have done it. If He were to do it, He would do so only if He were able to do it. The Quran thus establishes that He is able to do it and would do it if He willed it, even though He does not will it.
They also say that Allah knows the act as it truly is: He knows it to be possible and within the servant’s capacity, yet not occurring or coming into existence because the servant does not will it, dislikes it, or for some similar reason—not because he is incapable of it.
