Jewish Law

In Jewish law derived from the Talmud and rabbinic tradition, the age of three is explicitly discussed as the age at which a girl is considered fit for marriage (kiddushin). This is not a fringe opinion — it is discussed in mainstream Jewish legal works. Rashi's calculation that Rebekah was three when she married Isaac is consistent with this legal framework. The point is that if you want to criticise the Prophet Muhammad ﷺ for Aisha's age — which, as I showed, is not even from the Prophet ﷺ directly and varies between 6 and 7 — then you need to address why your own most authoritative commentator says a three-year-old was married in the Torah.
