While my mother did the customary Namaz five times a day, my father used to attend public lectures on Vedanta and other related topics by eminent experts. He got up early in the morning and did his yoga rituals. Being a Muslim did not preclude him from practising it. In fact, if you look closely, Namaz (Salat)--the daily prayers of Islamic religion--incorporates many simple asanas. The resemblance between Namaz postures and Yog-asanas like Qiyam and Namaste, Ruk'u and Ardha Uttanasana, Julus and Vajrasana, and finally, Sujud and Balasana are quite striking.
