In fact, the researcher can easily find the roots of humanism in the Holy Quran, the sayings of the Prophet and the writings of Muslim thinkers and scholars in the early ages of Islam.
Pairedly, we find many generous verses that honor and praise the human being to the point of asking the angels to prostrate to him, emphasizing that he carries a breath of Gods Spirit and his succession on earth, granting him the right to self-determination, reverence for his work, equality among his members and harnessing the universe for him.
The early Muslims understood this human tendency in the Quran and wrote about it and its revelation until it reached its climax in the fourth century AH at the hands of the Mu'tazila and writers such as Abu Hayyan al-Tawhidi, Miskawayh, Ibn Rushd and others.
