Surah 65:6:
...And if they breastfeed for you, then give them their due compensation (fa-ātūhunna ujūrahunna). And settle among yourselves with kindness..."
Verse 6 treats the postpartum care of infants through a strictly transactional, financial lens. It dictates that if a divorced woman breastfeeds her own biological child, her ex-husband is legally obligated to pay her a cash wage (ujūr) for her labor. If the parents cannot agree on a financial rate, the text suggests hiring a separate wet-nurse.
To a social historian, this language perfectly mirrors the mercantile, patriarchal economy of the Hijaz. Children are legally framed as the exclusive lineage and economic property of the father.
The mother's maternal investment is broken down into a commodified, billable service that can be bought, sold, or outsourced, illustrating how early Islamic family law adapted itself directly to the local trade-and-property paradigms of 7th-century Arabian merchants.
