Sayyiduna Jabir (may Allah be pleased with him) narrates that we were with the Noble Prophet (peace and blessings be upon him) in a battle. He (peace be upon him) would perform voluntary prayers on his mount facing towards the east. Then, when he wished to perform the obligatory prayer, he would dismount and pray facing the Qiblah. Imam Abu Bakr (may Allah have mercy on him) says that Muhammad bin Thawban refers to Muhammad bin Abdur Rahman bin Thawban; his attribution is to his grandfather Thawban instead of his father.
