Abbad bin Tamim reports from his uncle Abdullah bin Zayd (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) went out to the prayer ground seeking rain. He (peace and blessings be upon him) turned his cloak around, faced the qiblah, and prayed two rak'ahs.
Al-Mas'udi said: I said to Abu Bakr: Did he (peace and blessings be upon him) put the right side on the left and the left on the right, or did he put the upper part at the bottom? He said: Rather, he put the right side on the left and the left side on the right.
