It is very crucial that Muslims become very high quality people as soon as possible. It is very important that they bring quality to the forefront, that they attach importance to science, art and love and that they become peaceful. A feeling of hatred develops in the hearts of people towards people full of hatred. And then they become very determined and very decisive to kill them. Bigotry and lack of quality is a grave danger, lovelessness is a grave danger. - Harun Yahya
