Murrah said: I entered the mosque and said (to myself): I will pray at every pillar. Then I came to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him); he was sitting with his companions around him, and they were talking about me. He said: "If the one praying knew that his Lord is at the very first pillar, he would not leave it until he had completed his prayer."
