It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, in the mosque there is a spot in front of this pillar; if people knew (its virtue), they would not agree to pray there except by drawing lots."
At that time a group of the Companions and of the sons of the Muhajirun was with her (may Allah be pleased with her). They said: "O Mother of the Believers! Where is that spot?" But she (may Allah be pleased with her) did not make the spot clear to them (she kept it hidden). So they stayed with her (may Allah be pleased with her) for a while and then left, while Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) remained there. Those people said (to one another): "Sayyidah Aishah (may Allah be pleased with her) will surely tell him about that spot." So they kept watch on him in the mosque to see where he would pray. After a little while he came out and prayed beside the pillar beside which his son Amir bin Abdullah bin al-Zubayr (may Allah have mercy on him) used to pray, and that pillar is called "Ustuwanat al-Qur'ah" (the Pillar of the Lot).
Atiq (may Allah have mercy on him) said: "It is the pillar that stands in the middle between the (blessed) grave and the pulpit. From it, on its right side, to the pulpit there are two pillars; between it and the pulpit there are also two pillars; and between it and the courtyard of the mosque there are also two pillars. It is in the middle of all of these, and it is called 'Ustuwanat al-Qur'ah'."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Hisham (may Allah have mercy on him) except the two sons of al-Mundhir (Abdullah and Muhammad), and Atiq bin Ya'qub (may Allah have mercy on him) is alone in narrating it."
