This is and has always been the first question in this respect. Many of the thinkers are of the opinion that it is impossible to identify the truth correctly. They maintain that it is the lot of man not to know exactly what really in this world is and what passes in it. They consider it impossible to gain an indisputably accurate knowledge conforming to reality.
However, the Holy Qur'an regards it possible to know the truth.
It invites man to know Allah, the world, himself and history. In the story of Prophet Adam, which is really the story of man, it considers him to be fit to learn all the Divine names or the realities of the world. The Holy Qur'an says that in certain cases human knowledge can comprehend some items of Divine knowledge:
"They cannot comprehend anything out of what He knows save what He wills." (Surah al-Baqarah, 2:255)
