The Holy Qur’an and Free Will
The Holy Qur’an states this issue directly and proves the free will of human beings and there are hundreds of verses which talk about free will.
All of the verses which relate to commanding virtue and preventing vice are all proof of the free will of human beings because if a person was destined to do so, commanding them to do so would make no sense.
All of the verses which speak of blame and reproach against the evil doers and praise for the good doers are proof of free will because if one was destined to do whatever one did, blame or praise would make no sense.
All of the verses which speak about the questioning on the Day of Judgement and the Judgement in that Court and then the rewards and punishments and heaven and hell are proof of free will because if one was to assume that everything was predestined then questioning, judging, rewards and punishments would all be oppressive.
Some explicit verses of the Qur’an which say that a human being is responsible for his or her deeds are:
“Every soul will be (held) in pledge for its deeds.” (Surah Muddathir, 74: 38).
“(Yet) in each individual in pledge for his deeds.” (Surah At-Tur, 52: 21).
“We showed him the Way: whether he be grateful or ungrateful (rests on his will).” (Surah Al-Insaan, 76:3).
“But you will not except as God wills…” (Surah Al-Insaan, 76:30).
