How can Muslim women be convinced of the prohibition of wearing perfume when leaving the home, and what is the ruling on one who does so and whose scent is perceived?

May Allah reward you for your eagerness to guide your sisters. Know that Islam blocked the means to evil and prohibited women from wearing perfume in front of non-mahram men, due to its negative effect on men's hearts.

On the authority of Abu Musa Al-Ash'ari, who said: The Messenger of Allah, peace and blessings be upon him, said: "Any woman who perfumes herself and passes by people so that they may smell her fragrance is a fornicator."

And on the authority of Zaynab Ath-Thaqafiyyah, that the Prophet, peace and blessings be upon him, said: "If one of you goes out to the mosque, she should not approach perfume."

And on the authority of Abu Hurairah, who said: "A woman passed by him, and her fragrance was strong. He said: 'O handmaiden of the Almighty, do you intend to go to the mosque?' She said: 'Yes.' He said: 'And for it have you perfumed yourself?' She said: 'Yes.' He said: 'Then go back and perform ghusl, for I heard the Messenger of Allah, peace and blessings be upon him, say: 'No prayer of a woman who goes out to the mosque with a strong fragrance will be accepted by Allah until she returns to her house and performs ghusl.'"

And if the prohibition of perfuming oneself applies when a woman goes out to the mosque, then it applies even more so when she goes out to other places. Umar, may Allah be pleased with him, used to strike with his whip any woman who perfumed herself and would say: "You perfume yourselves, and you know that men's hearts are at their noses."

A sincere Muslim woman, upon hearing these texts, will fear falling under the threat of this warning. A Muslim does not need more to convince him than the words of Allah and His Messenger.
