What is the ruling regarding the ihram of a woman who arrived in Mecca while menstruating, without having intended to perform Umrah from the Miqat, and then bathed and entered into ihram from Al-Taneem to perform Umrah?

If she entered Mecca without the intention of performing Umrah, then intended it and entered into Ihram from Al-Taneem, there is nothing upon her. However, if she intended Umrah and passed the Miqat while menstruating, intending to delay her Ihram until she became pure, then she must slaughter a sacrifice (dam) to be distributed among the poor of the Haram, because ritual purity is not a condition for Ihram, and the Prophet, peace and blessings be upon him, set the Mawaqit "for whoever intends Hajj and Umrah."
