1. We abide to the meanings of Quranic verses and rules of Islam as explained by the Prophet Muhammad (SAWA) and his Holy Progeny Ahlul Bayt (AS), and not our own thinking or our superficial linguistic understanding which is away from what the Prophet and Ahlul Bayt have explained.
2. Khums consist of two equal parts; Sahm Imam, and Sahm Sadat. Sahm Sadat is the right of needy Sadat who ae from the family tree of the Prophet (SAWA). Allah (ST) knows that Ahlul Bayt (AS) and their families will face big difficulties from their enemies, that is why, Sahm Sadat has been ordained for the needy Sadat.
3. Sahm Imam (AS) is the right of the Imam (AS) and it is received either by him or by his deputies like the Marja' of Taqleed or his deputies now a days. Sahm Imam is used generally in serving the general poor and needy and religious, educational and social services.
