If Allahu ta’ala did not create His works through intermediaries, no one would need anybody else; everybody would ask everything directly from Allahu ta’ala and would have recourse to nothing; there would not be social relations between people such as the superior and the subordinate, foreman and workman, pupil and teacher and so forth, and thus this world and the next would be in disorder and there would not be any difference between the beautiful and the loathsome, good and evil, the obedient and the disobedient.
If Allahu ta’ala had willed, He would have created His Custom in some other way and He would have created everything according to it. For example, if He had willed, He would put disbelievers, those who are addicted to pleasures in the world, those who hurt others and the deceitful into Paradise, and He would put the faithful, worshippers and the benevolent into Hell. But ayats (verses of al-Qur’an al-karim)and hadiths (saying of the Prophet ‘alaihi ‘s-salam) show that He did not will so.
He is the One who creates all optional or voluntary and involuntary actions and movements of human beings. He created ikhtiyar (option) and irada (will) in born slaves for His creating their optional, voluntary actions, and made this option and will a means for creating their actions. When man wants to do something, Allahu ta’ala creates this action if He wills, too. If man does not want or will and if Allahu ta’ala does not will, either, He does not create. Allahu ta’ala creates upon not only man’s wish; He creates if He wills, too.
