Who wrote the Koran? What are the most controversial passages ?

The Qur'an, also spelled Quran or Koran, is considered by Muslims to be the direct word of God as revealed to the Prophet Muhammad over a period of 23 years. The revelations were memorized and written down by his followers, and were later compiled into a single book in the 7th century.

As for the most controversial passages in the Qur'an, there are several verses and interpretations that have been the subject of debate and conflict, both within the Muslim community and between Muslims and non-Muslims. Some of the most commonly cited controversial passages include:

1. Violence and warfare: There are verses in the Qur'an that speak of violence and warfare, and these verses have been used to justify acts of aggression and terrorism by some extremists. However, most Muslims interpret these verses as referring to specific historical circumstances and as only permitting defensive warfare in response to aggression.

2. Women's rights: There are verses in the Qur'an that address the role of women in society, and these verses have been interpreted differently by different Muslims and have been used to justify varying positions on issues such as marriage, divorce, and dress codes.

3. Punishments: The Qur'an contains verses that describe punishments for certain crimes, such as theft and adultery. These verses have been used to justify harsh punishments, including amputations and stoning, in some Islamic countries, which are considered controversial and inhumane by many.

4. The treatment of non-Muslims: There are verses in the Qur'an that address the treatment of non-Muslims, and these verses have been used to justify varying attitudes towards non-Muslims, from tolerance and coexistence to intolerance and hostility.

It's worth noting that the interpretation of these and other controversial passages in the Qur'an is a matter of ongoing debate and discussion within the Muslim community, and that there is significant variation in how these verses are understood and applied by different Muslims and Muslim communities.
