Machine translationRead the Arabic original
The questioner:
If I have a son who is twelve years old, is he a mahram to his sister, and can they go to the market together?
The Shaykh:
One is not a mahram unless he is an adult, a sane adult. It is a condition for a mahram that he be an adult and sane. Yes.
The questioner:
He says: What about…
The Shaykh:
The market does not require a mahram, but it was said that he may go with her to protect her, serve her, and look after her, and there is nothing wrong with that. This is not a matter of mahram status; this is a matter of protection and care. Yes, and helping her. Yes.
