This is the verse translation, not a definition of the individual word.
Mothers[1] may breastfeed their children for two full years, for those who wish to complete the full term of breastfeeding. It is the obligation upon the father of the child that he provides food and clothing [for the mothers] with fairness. No soul is obligated beyond what it can bear. Neither mother nor father should be made to suffer on account of their child, and the same duty is incumbent on the heir. If they both decide on weaning, by mutual consent and consultation, there is no sin on them. And If you wish to provide a wet nurse to your children, there is no sin on you, if you pay in full what you have agreed upon with fairness. But fear Allah and know that Allah is All-Seeing of what you do.
