question #2 Sahih al-Bukhari 1760, 1761, Book 25, Hadith 237 : How did the understanding of Ibn `Umar change regarding the departure of menstruating women from Mecca?

A menstruating woman was allowed to leave Mecca if she had done Tawaf-al-Ifada. Tawus (a subnarrator)
said from his father, “I heard Ibn `Umar saying that she would not depart. Then later I heard
him saying that the Prophet (ﷺ) had allowed them (menstruating women) to depart.”
