It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that on the occasions of the two Eids, during travel, a spear would be taken along with the Prophet (peace and blessings be upon him), which would be planted in front of the Prophet (peace and blessings be upon him), and making it a sutrah, the Prophet (peace and blessings be upon him) would lead the prayer.
