Khums must be divided into two parts: one part is the portion for sayyids[1] (sahm al‑sādāt), which must be given to a poor sayyid, an orphan sayyid, or a sayyid who is stranded on a journey. The second part is the portion for the Imam (ʿA) (sahm al‑imām), which at present [i.e. during the time of the Imam’s (ʿA) occultation] must either be given to a fully qualified jurist or spent for purposes that he authorises.
And the obligatory precaution is that the jurist must be the most learned (aʿlam) marjaʿ[2] and be well aware of public affairs.
