Everything is written, maktoub, we can do nothing. Generally, the will of Allah is thought to be like the application of a pre-written program, in the way of a book or, as we could say nowadays, of a computer program. Certain Muslim sages would like to speak as Christians do, associating the notions of human free will and the omniscient Will of God. But they hit against several suras of the Koran that affirm predestination, which is one of the principles of Muslim belief [1]. We can but accomplish what Allah has written for us (Sura “The Repentance” 9, 51). A man may be (well) guided by Allah, but also the reverse: Allah can equally lead him astray, and then he is lost (Sura “The Wall of A’raf” 7, 178-179).
A famous Hadith says this: ‘[Into the embryo in the womb of his mother] the angel breathes the vital spirit and ordains four prescribed words: his subsistence, the end of his life, his actions, and his happiness or misery. I swear on Allah, outside of which there are no other gods, that the one who acts with the people of paradise even to be so close to them as the distance of an arm, will be crushed according to what is prescribed for him: he will act like the people of hell and he will go to hell. The one who acts with the people of hell even to be so close to them as the distance of an arm, will be returned according to what is prescribed for him: he will act like the people of paradise and he will go to paradise” [2].
All would be written in advance, including the eternal destiny in Paradise or in Hell. An eternal decree has even decided that some will not believe (Sura “Ya’ Sin” 36, 7-10).
Thus, this dogma conducts next to a division of humanity between those who are predestined to heaven and those who are predestined to hell.
