How long should the deceased's clothes be distributed, and is it necessary for this to be within three days of his death?

There is nothing in Islamic law that mandates the distribution of a deceased person's clothes within three days of their death, as the default rule is that no specific timeframe is obligatory in this regard. The deceased's clothes are part of their estate, which is to be divided among the heirs according to the Islamic legal system. The person in charge of these clothes may keep them for themselves or donate them at any time they wish.
