Does a brother have guardianship over his sister in the absence of the father? And does he change evil by his hand, such as preventing her from going out wearing perfume, or breaking her perfume? Or does he not have guardianship over her because he does not financially support the household? And is she obliged to seek his permission when going out? And does he prevent her from spending the night at her friends' houses if they have brothers?

The brother has guardianship over his sister in the father's absence, which is a guardianship of preservation and care, not of dominance. Therefore, it is permissible for the brother to prevent his sister from living alone if she has no father, and from going out perfumed in a way that might lead to temptation, or from spending the night in an unsafe place. This prevention is for the purpose of warding off evil and protecting his sister from corruption, and it is a duty upon everyone who is able to do so. The brother is advised to be gentle and wise in dealing with his sister.
