The World Federation One Stop Fiqh

Ruling 1858

If one’s wife is a sayyidah,21 then based on obligatory precaution he must not give his khums to her to spend on her living expenses [that are obligatory for him to provide]. However, if it is obligatory for her to meet the living expenses of others but she cannot do so, it is permitted (jāʾiz) for him to give his khums to her to spend on them. The same applies [i.e. as with the case mentioned at the beginning of this ruling, he must not, based on obligatory precaution,] give his khums to her to spend on her maintenance (nafaqah) that is not obligatory for him to provide.

21 A sayyidah is a female descendant of Hāshim, the great grandfather of Prophet Muḥammad (Ṣ).
