Yazid bin Abi Ubayd relates: I used to come with Sayyiduna Salamah bin al-Akwa' (may Allah be pleased with him) to the Prophet's Mosque, and he would pray beside the pillar where the copy of the Qur'an was kept. Once I said: "O Abu Muslim, I see that you pray beside this pillar." He said: "I saw the Messenger of Allah (peace and blessings be upon him) making a point of praying in front of it."
