Would a girl be sinful if she prevented her brother, who neither works, prays, nor fasts, and smokes hashish, from living with her in the cramped charitable family housing, knowing that she did not prevent him from visiting?

We pray to Allah to facilitate your marriage to a righteous man, and we advise you to supplicate frequently, for sustenance is decreed. It is permissible for a woman to seek a husband and offer herself to whomever she wishes to marry, while observing the limits set by Allah. Regarding housing, the matter depends on the granting authority. The issue should be resolved through understanding to avoid problems, and it is advised to gently encourage the brother to abandon sinful acts. If he does not repent, there is no harm in shunning him if shunning is beneficial. It is strange for the brother to be a burden on you while he is capable of earning a living. The maintenance of a poor mother is obligatory upon her affluent children. The maintenance of other relatives is obligatory upon the inheriting relative, under certain conditions.
