Muhammad bin Abi Yahya relates: I saw Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both); he saw a man raising his hands for supplications before finishing his prayer. When the man had finished it, he said: "The Messenger of Allah (peace and blessings be upon him) would not raise his hands until he had finished his prayer."
