Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that I saw the Messenger of Allah (peace and blessings of Allah be upon him) performing prayer in the Eid ground, taking a spear as a sutrah. Imam Abu Bakr (may Allah have mercy on him) says that from the command of the Prophet (peace and blessings of Allah be upon him) to use an arrow as a sutrah in prayer, it becomes clear and established that in the command to use the rear wooden part of a saddle as a sutrah, what the Prophet (peace and blessings of Allah be upon him) meant was its length, not both its length and width.
