Salamwalayykumm. Is HY human? Of-course he is. So its human to make error [although strictly speaking, this is a huge error], the way forward for him is to apologize and move forward. My humble opinion. Do I need to write about Harun Yahya after all this? His scholarship on many matters nobody can deny. Again he is looked up-to. As a Scholar. Have we made takfir of him? No, we haven't. We are only saying, his hobnobbing with women is wrong. And because he is looked up-to as an 'Islamic' personality, his amal's will also be copied, if he is lax with regards to matters regarding women, then we too will be influenced sooner rather than later. Lets hope we all are guided and kept on guidance for-ever, summa aameen.
