Saeed bin Yasar narrates: I was traveling with Sayyiduna Abdullah bin Umar (may Allah be pleased with him) on the way to Makkah. When I feared that dawn was near, I got down from my mount and performed Witr. Then I reached Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), and he asked me: Where were you? I replied: I feared that dawn was about to break, so I got down from my mount and performed Witr. Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) asked: Is there not an example for you in the way of Allah’s Messenger? I replied: Yes, there is. He said: The Prophet (peace and blessings be upon him) used to perform Witr on his camel.
