Adnan Oktar has also produced various works on Zionist racism and Freemasonry and their effects on world history and politics. Besides these, he has written more than a hundred books describing the morals of the Qur'an and faith related issues. The common point in all of Yahya Harun's works is that all the topics covered by his works are in full agreement with Qur'an, and strongly affirmed by Qur'anic understanding. Even the topics addressed by science and mostly considered complicated and confusing are narrated very lucidly and explicitly in his books. For this reason, these books appeal to everyone, from every age and social group. Harun Yahya's books on faith-related topics communicate the existence and oneness of Allah and are written with the main purpose of introducing Islam to those who are strangers to religion, and reconciling their hearts to the truth. For Muslims, these books are advice as well as a reminder. He has published works on all the basic issues referred to the Qur'an that expand the dedication and contemplation of Muslims. Harun Yahya's stresses in his books on science-related topics the might, sublime, and majesty of Allah in minute detail based on well-structured research and evidence, along with extensive contemplation. These books display, for non-Muslims, the signs of the existence of Allah, and the excellence of His creation in a very explicit and precise way. Adnan Oktar was born in Ankara.
