Musannaf Ibn Abi Shaybah 18859 — A man who says to his wife "Observe

Shu'bah said: I asked al-Hakam (may Allah have mercy on him) and Hammad (may Allah have mercy on him): if a man says to his wife, "You are divorced, you are divorced, you are divorced," and intends only one divorce, what is the ruling? They both said: Only one divorce takes effect; and if he says, "Observe your waiting period, observe your waiting period," the ruling is the same.
