People posting on this thread seem to have grave misunderstandings regarding Qadar of Allah (i.e. the Will or Decree of Allah).
It should be pointed out here that nothing happens in the heavens and the earth except that it has happened by the Will of Allah. To say that things happen without the Will of Allah is to say that Allah is ignorant of so-and-so, and we cannot attribute ignorance to Allah. To believe in Qadr is a part of faith and ones belief is not valid unless we believe in the four aspects of Qadar. They are as follows:
1 – Belief that Allah knows all things, in general terms and in detail, from eternity to eternity. Not a single atom is unknown to Him in the heavens or on earth.
2 – Belief that Allah has decreed all things in al-Lawh al-Mahfooz (The Preserved Tablet), fifty thousand years before He created the heavens and the earth.
3 – Belief that the will of Allah is irresistable and His decree is comprehensive, so nothing happens in this universe, good or bad, but by His will.
4 – Belief that all that exists was created by Allah. He is the Creator of all beings and the Creator of their attributes and actions, as He says (interpretation of the meaning):
Such is Allaah, your Lord! None has the right to be worshipped but He, the Creator of all things [al-An’aam 6:102]
There is much more to Qadar then this and it is an integral part of belief to believe that everything that happens is because of the Will of Allah and had it not been His Will then so-and-so thing will not take place.
