It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) made his camel sit down in the plain of Dhul-Hulaifah, then he (peace and blessings be upon him) performed prayer there, and Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to do the same.
