In the incident of the conquest of Bayt al-Maqdis, various narrators mention that Sayyiduna Umar (may Allah be pleased with him) asked Ka'b al-Ahbar, "In your opinion, where should I pray?" He replied, "If you want to act upon my opinion, then pray behind the rock, so that the entire Bayt al-Maqdis will be in front of you." Umar said, "You have spoken like the Jews; this cannot happen. I will pray at the place where the Prophet (peace and blessings be upon him) prayed on the night of Mi'raj." Thus, he moved towards the qiblah and prayed there. After the prayer, he spread out his cloak and gathered all the rubbish of that place in his cloak, and the people followed him in this.
