Musannaf Ibn Abi Shaybah 18839 — A man who divorces his wife once

Ibn Ma'qil (may Allah have mercy on him) and al-Sha'bi (may Allah have mercy on him) said: If a man gives his wife one divorce, then a man meets him and asks, "Have you divorced your wife?" and he answers, "Yes, I have," then another man meets him and asks the same question and he answers, "Yes, I have" - if in answering them he intended the first divorce, then the divorce remains only one.
