Abdullah bin Umar reported,

Ibn Umar divorced his wife while she was menstruating. Umar mentioned this to the Prophet ﷺ, and the Messenger of Allah ﷺ said, "Let him take her back until she becomes pure, then let him divorce her."The narrator said, I asked, "Should that divorce be counted?"He replied, "Of course."
