Is it permissible to say that “Allah predestined so, what can I do?” The short answer is…
Belief in destiny and Allah’s decree (qadar and qada) is among the pillars of faith. However, humans cannot free themselves from responsibility by using destiny as an excuse. Just like it would not be appropriate for a person to commit a crime by saying, “Allah predestined so, this was my destiny, what can I do?”, it is not permissible for him to plead himself not guilty by using destiny as an excuse.
The servant is the one who wills the actions that create responsibility, but he is not the creator of them; because Allah is the only Creator. It is stated in the Holy Qur’an, “That is Allah, your Lord; there is no deity except Him, the Creator of all things, …” (An’am, 6/102). The fact that Allah is the Creator of all the things should not lead us to free ourselves from responsibility and leave all the bad and wrong deeds to Allah. This will be exploitation of qadar. Moreover, it is incompatible with the Islamic understanding of destiny to stop working by relying on fate and destiny, not to hold on to the necessary reasons and take the necessary measures to ensure positive results or prevent negative consequences. Because Allah linked everything to certain causes. If humans fulfill these reasons, Allah creates their results. This is a divine law and qadar.
Consequently, it is not appropriate for people to say, “What can I do, this is my destiny.” As humans are free in the area where people are responsible towards Allah, they will be questioned for their belief and actions.
