Abdullah bin Umar reported,

I divorced my wife while she was menstruating, so Umar came to the Prophet ﷺ and informed him. He said, "Order him to take her back, then when she becomes pure, let him divorce her."I asked Ibn Umar, "Was that pronouncement counted as a divorce?"He replied, "Of course."
