According to the Malaysian Star, "Recently, lecturer Prof. Zakaria Stapa of Universiti Kebangsaan advised Muslims who had taken up yoga to stop practicing it for fear that they could deviate from the teachings of Islam." This triggered a national debate, resulting in the announcement by The National Fatwa Council that it would issue an official ruling about yoga. This decision has been temporarily postponed. Reports Brunei News, "The Department of Islamic Development Malaysia Director-General Wan Mohamad Sheikh Abdul Aziz said his department had carried out an in-depth study on the issue over six months and regretted the attitude of Malaysian Muslims who were 'easily influenced by foreign cultures to the point of affecting their faith.'"
This seems to be a prevalent discussion among people of many different faiths. Why do you think religious leaders fear yoga will adversely affect their followers?
