Al-Baqarah 2:233 ۞ والوالدات يرضعن اولادهن حولين كاملين لمن اراد ان يتم الرضاعة وعلى المولود له رزقهن وكسوتهن بالمعروف لا تكلف نفس الا وسعها لا تضار والدة بولدها ولا مولود له بولده وعلى الوارث مثل ذالك فان ارادا فصالا عن تراض منهما وتشاور فلا جناح عليهما وان اردتم ان تسترضعوا اولادكم فلا جناح عليكم اذا سلمتم ما اتيتم بالمعروف واتقوا الله واعلموا ان الله بما تعملون بصير ٢٣٣

Mothers shall suckle their children for two whole years; (that is) for those who wish to complete the suckling. The duty of feeding and clothing nursing mothers in a seemly manner is upon the father of the child. No-one should be charged beyond his capacity. A mother should not be made to suffer because of her child, nor should he to whom the child is born (be made to suffer) because of his child. And on the (father's) heir is incumbent the like of that (which was incumbent on the father). If they desire to wean the child by mutual consent and (after) consultation, it is no sin for them; and if ye wish to give your children out to nurse, it is no sin for you, provide that ye pay what is due from you in kindness. Observe your duty to Allah, and know that Allah is Seer of what ye do.
