Salaam. I am a Muslim and I like watching anime and reading manga. I usually watch action, adventure types and block tags that contain mature content. I wanted to ask if I am allowed to do so? Another question I have is about drawing. What has been said about drawing cartoons and such? Jazakullah Khair.
There is nothing wrong with anime and manga inherently. It is however against Islamic manners to seek sexual pleasure outside of marriage, therefore if those “mature” blocks you describe are there for the reader’s sexual enjoyment, then it is not acceptable for you to peruse them. You can skip those pages and scenes that are designed to be sexually suggestive and enjoy the rest.
Since we can never be sure if God will be pleased with us if we seek sexual enjoyment outside of marriage in any form, no one who truly loves and fears God will risk disrespecting and angering Him through such things, even if it is in a seemingly unimportant matter.
The Azhari scholars (from al-Azhar University in Cairo) Gad al-Haq Ali and Yusuf al-Qaradhawi and the Saudi Islamic studies professor Khalid bin Abdullah al-Qasim say that drawing (including drawing living things) is permissible. You will find others who will say that drawing living things is not permissible. The people of Egypt and most of the Muslim world follow the Azhari opinion.
