Shaykh al-Islām—may Allah Most High have mercy on him—was asked:

“Do divine decrees entail wisdom or not? If they entail wisdom, has Allah willed that people do what they actually do? And if His will has preceded their actions, what does it mean for there to be an excuse under these circumstances? Please give us a ruling; may you be rewarded.”

He replied:

All praise is due to Allah, Lord of the worlds. Our Lord, glorified and exalted is He, encompasses everything in knowledge, power, and rule; His mercy and knowledge embrace all things. There is not an atom in the heavens or the earth, nor any meaning whatsoever, that does not testify to Allah Most High’s complete knowledge and mercy and His perfect power and wisdom. He did not create creation without purpose, nor has He done anything in vain. Rather, He is wise in His actions and His words—glorified and exalted is He. Some aspects of His wisdom He has disclosed to some of His creatures, while knowledge of others He has reserved for Himself.

His will is of “two kinds”: the will pertaining to command and legislation, and the will pertaining to decree and ordainment.

The first kind pertains only to acts of obedience, not sins, whether those acts occur or not. As He says:

“Allah intends to make things clear to you, guide you to the ways of those before you, and accept your repentance.”

And He says:

“Allah intends ease for you and does not intend hardship for you.”
