Sayyiduna Mu'ayqib bin Abi Talhah (may Allah be pleased with him) narrated that the Prophet (peace and blessings of Allah be upon him) said to a man who used to level the pebbles every time he prostrated: "If you must do so, then do it only once (because doing it repeatedly is against humility and submissiveness in prayer)."
