Explanation of the author's words: And his saying: (And if Allah had willed, they would not have fought, but Allah does what He wills)

The Shaykh : Here he says: The word "law" (if) is a particle of negation for the sake of negation, and if its answer is negative, the most eloquent is to omit the lam and if it is affirmative, the most common is to keep the lam This is the answer to "law": if it is negative, the most eloquent is to omit the lam, and if it is affirmative, the most common is what we say is the most eloquent, because the presence and omission of the lam have both occurred in the Noble Qur'an So the most common is to keep the lam. Now, we said that the most eloquent is to omit the lam in the negative. Why? Because the lam implies emphasis, and negation contradicts emphasis. For this reason, the poet's saying:
"And if we were given the choice, we would not have separated"
was contrary to the most eloquent, and the most eloquent is:
"And if we were given the choice, we would not have parted *** But there is no choice with the days".
Now he says: To whom does the pronoun refer? To the believers and the disbelievers, by His saying, the Exalted: And in this is a clear refutation of the Qadariyyah who deny that the action of the servant is connected to the will of Allah, because Allah said and its opposite, but He willed that they should fight, so they fought. And with this, it is a clear refutation of the Qadariyyah who denied that the actions of the servants are connected to the will of Allah, Mighty and Majestic.
Then he said: The will here is cosmic will. And "does" means He decrees, Mighty and Majestic, that He does, if it is with regard to the servants. And "does" if it is with regard to Him, meaning if He wills something, He does it. It may be said that the verse is absolute: He does what He wills. So the action, in consideration of what He, Glorified and Exalted is He, does with Himself, is direct action, and in consideration of what He decrees upon the servants, it is indirect action. Otherwise, it is known that if a person fasts, prays, gives zakah, performs ablution, performs Hajj, and fights, who is the doer? The human being, without doubt. And it is known that his action is by the will of Allah. And it is not correct to attribute the action of the servant to Allah by way of directness, because the one who is direct in the action is the human being. But it is correct to attribute it to Allah by way of decree and creation. As for what Allah does with Himself, such as His rising above His Throne, His speech, His descent to the lowest heaven, His laughter, and the like of that, this is attributed to Allah, the Exalted, as direct action Which of the two wills? The cosmic, not the legislative, because in the legislative, Allah may will something and not do what He decrees. Allah, Mighty and Majestic, wills from everyone that they believe in Him, but does everyone believe? No.
