No, I doubt they are Muslim.
It is haram for men to imitate women and women to imitate men.
Ibn ‘Abbaas (may Allaah be pleased with him) reported that “The Messenger of Allaah
(peace and blessings of Allaah be upon him) cursed men who make themselves look like women and women who make themselves look like men.” (Reported by al-Bukhaari, 5435).
Abu Hurayrah said: “The Messenger of Allaah
cursed men who wear women’s clothes and women who wear men’s clothes.” (Reported by Abu Dawood in al-Sunan, Kitaab al-Libaas, Baab fi libaas al-nisaa’).
I have read about some men in saudi wearing niqab so they could spy on women, astaghfirullah. THey went to a wedding and were found out, because everyone removed their veil.. apart from the two suspicious guys sitting in the middle of the hall. lol
wasalam.
