What is the ruling on eating food prepared by a woman during her menstrual period?

A woman's menstruation affects only prayer, fasting, and sexual intercourse. All other interactions, such as eating and sleeping with her, are permissible. Everything that a menstruating woman prepares, whether food, drink, clothes, or utensils, is pure. It is permissible for her husband to eat with her, based on the hadith of Aisha (may Allah be pleased with her) that the Prophet (peace and blessings of Allah be upon him) used to eat with her and place his mouth where her mouth had been on a bone with meat (al-ʿarq) and in a cup while she was menstruating. This hadith explicitly indicates the purity of a menstruating woman.
