Yoga is olde than 5000 years ago and surya namaskar so far i can see Salah is that practice too etc .. Muslims in my optiek must overthink this all if yoga is good or not .. So far I believe Dr Zakir Naik is not really able to tell The Truth of Yoga .. Just a fraction on Vivekanda is only consider by me truthfull said by DR Zakir Naik .. Who Am I to say this dr Zakir must question too just like all other moslim speekers in the world today!!!!! Salam Alaikum!!!!!
Yoga means Union with God and so Tawheed measn the same namelijk to make One with Allah.. Salaah is likely Surya Namaskar.. The onley thing is that many in hinduisme do not believe in One God.. but in many! Iesa moi
