Is facing the qiblah required for the opening takbir in a voluntary prayer while riding?

Question:
May Allah reward you, Honorable Shaykh. This questioner asks: Is it required to face the qiblah at the start of a voluntary prayer if one is praying it while riding during travel?

Answer:
No. The jurists mentioned this, but there is no evidence for it. Yes, they say that the one who walks does not, but the one on a mount does not, according to all of them. However, they say that the one who walks faces the Ka'bah at the opening takbir and then proceeds in the direction he is walking, and there is no evidence for this. Yes, there is no difference between the one who walks and the one who is riding.
