سورة الأحزاب

Imam Kazim (peace be upon him): Whoever's mother is from Banu Hashim and whose father is from the other families of Quraysh, sadaqa (charity) is permissible for them, and they have no share of khums; for Allah the Mighty and Majestic says: ادْعُوهُمْ لِآبَائِهِمْ [Assert their relationship to their fathers].

Imam Rida (peace be upon him): Muhammad ibn Sinan said: Imam Rida (peace be upon him) wrote in reply to his questions: ... The reason for the permissibility of the son's property for the father without his permission — while the father's property is not permissible for the son without his permission — is that the son is a gift bestowed upon the father. Allah says in this noble verse: "He grants daughters to whomever He wills, and grants sons to whomever He wills." (Shura/49) In addition, the father is answerable for the son's maintenance, whether young or old (the father is his provider), and the son is attributed to him and called by his name — on the basis of this saying of Allah: ادْعُوهُمْ لِآبائِهِمْ هُوَ أَقْسَطُ عِنْدَ اللهِ [Assert their relationship to their fathers; this is more equitable with Allah]; and on the basis of this saying of the Prophet (peace be upon him and his family): "You and your property belong to your father. But the mother is not like that."
