The word(s) "idolatress" appears 3 time(s) in 2 verse(s) in Quran in Muhammad Pickthal translation.

(1) Wed not idolatresses till they believe; for lo! a believing bondwoman is better than an idolatress though she please you; and give not your daughters in marriage to idolaters till they believe, for lo! a believing slave is better than an idolater though he please you. These invite unto the Fire, and Allah inviteth unto the Garden, and unto forgiveness by His grace, and expoundeth His revelations to mankind that haply they may remember.

(2) The adulterer shall not marry save an adulteress or an idolatress, and the adulteress none shall marry save an adulterer or an idolater. All that is forbidden unto believers.
