The adjective "ignorant" as used in the Qur'an has a different meaning to what is generally understood. Ignorance expressed in the Qur'an means being unaware of the reason for one's creation, being unaware of the exalted attributes of our Creator Allah and the knowledge and wisdom contained in the Book which He has sent down, and being unaware of matters concerning the Hereafter and as a result of this ignorance adopting an unconscious life style.
The "ignorance" of people who do not accept Allah as the only true god and who do not follow the way He has sent with His messengers, is pointed out in the Qur'an as follows:
They said, "Have you come to us to divert us from our gods? Bring us what you have promised us if you are telling the truth." He said, "All knowledge is with Allah. I only transmit to you what I have been sent with. But I see that you are a people who are ignorant." (Surat al-Ahqaf: 22-23)
