Ibn Al-haaj (may Allah have mercy on him) mentioned that one of the bid?ahs on ?Aashooraa? was deliberately paying zakat on this day, late or early, or slaughtering a chicken just for this occasion, or -in the case of women- using henna. (Al-madkhal)
«May those who are fasting break their fast in your home, and may the dutiful and pious eat your food and may the angels send prayers upon you» [Abu Dawud, authentic].
