Q: Some people hasten to explain some matters to new Muslims, some of these matters may be minor details, for example, wearing the complete Hijab (veil) for women and growing a beard for men and circumcision and other such matters. Can you comment on this subject?
A: These are minor details, if they are clarified at the beginning, there is nothing wrong with that, and if they are delayed to a later time, there is also nothing wrong with that. The most important thing is to explain the basics of the religion so that the person can enter Islam. As for subsidiary matters like shaving the beard or shortening it, or wearing Hijab, or circumcision and the like, these should better be delayed to a later time so that the person is not repelled or discouraged and just to teach them the foundations of Islam first and its great pillars. After they embrace Islam, they can be encouraged to perform the rest of the practices of Islam.
