I was traveling with Abdullah bin Umar on the road to Makkah. Saeed said, When I feared that dawn was approaching, I dismounted and prayed witr, then caught up with him.Abdullah bin Umar asked me, "Where were you?"I said, "I feared dawn was near, so I dismounted and prayed witr."Abdullah said, "Do you not have in the Messenger of Allah an example to follow?"I replied, "Yes, by Allah."He said, "The Messenger of Allah ﷺ used to pray witr on his camel."
و حدثني عن مالك عن أبي بكر بن عمر
كنت أسير مع عبد الله بن عمر بطريق مكة قال سعيد فلما خشيت الصبح نزلت فأوترت ثم أدركته فقال لي عبد الله بن عمر أين كنت فقلت له خشيت الصبح فنزلت فأوترت فقال عبد الله أليس لك في رسول الله أسوة فقلت بلى والله فقال إن رسول الله ﷺ كان يوتر على البعير
