Huzayl bin Shurahbil (may Allah have mercy on him) says: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) came to our mosque, and the iqamah was called. We said: "Go forward and lead the congregation." He said: "Let your imam go forward and lead the congregation." We said: "Our imam is not present here." He said: "Then let someone else go forward." So that man stood on a raised platform in the mosque, and Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) forbade him from that.
