Is yoga haram? lets say my intention is not to pray like they do only to relax my mind etc?

According to the Azhar-educated scholar Dr. Ujail Al-Nashami¹ if yoga is done for health (exercise and meditation) then it is permissible, while the mystical and religious parts of it should be avoided. He says that once the health-related parts of yoga are isolated then it becomes merely a sport like other sports.

Due to its association with Hinduism and Buddhism most scholars appear to have a very negative view of yoga. But there is no reason why a Muslim cannot take the beneficial parts of yoga and make use of them while rejecting the prohibited parts of it. Mosque architecture was largely inspired by pre-Islamic religious architecture from Central Asia, but Muslims took it, avoided the anti-Islamic elements of it (such as statues of gods) and made it part of their own architecture. There is no reason why Muslims cannot do the same with yoga.
