Is the reward for charity (ṣadaqah), zakat, and ongoing charity (ṣadaqah jāriyah) performed by the husband limited to the husband alone, or does it include all members of his family, knowing that the wife does not work and has no income?

A Muslim is exclusively entitled to the reward for his good deeds, but it is permissible for him to donate the reward of his deed, or part of it, to a living or deceased Muslim. The recipient will benefit from this. Thus, any act of worship performed by a Muslim, where he dedicates its reward or a portion of it to a living or deceased Muslim, is permissible and beneficial to the latter.
