Shaykh Muqbil Bin Hadi Al-Wadi’i was asked:
“Is it permissible to give da’wah to non muslim women even if they are clothed but appear to be naked and bearing in mind that many of them have begun to embrace Islam?”
“This returns to the condition of the caller. If he fears fitnah for himself, then nothing is equal to keeping one’s heart safe [from fitnah] and if he is a person who has concern for eeman [i.e the religion] or for the Muslims, while a person’s eeman fluctuates. Sometimes a person may have with him much enthusiasm for the religion so nothing affects him [from fitnah]; if this is the case, then this is something good. However, if he fears fitnah for himself, then he should advise others who don’t fear fitnah for themselves to do it instead. May Allaah reward you with good for what you are doing. [i.e giving da’wah to non muslims]…” End translation.
