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 may nurse [i.e., breastfeed] their children two complete years for whoever wishes to complete the nursing [period]. Upon the father is their [i.e., the mothers'] provision and their clothing according to what is acceptable. No person is charged with more than his capacity. No mother should be harmed through her child, and no father through his child. And upon the [father's] heir is [a duty] like that [of the father]. And if they both desire weaning through mutual consent from both of them and consultation, there is no blame upon either of them. And if you wish to have your children nursed by a substitute, there is no blame upon you as long as you give payment according to what is acceptable. And fear Allāh and know that Allāh is Seeing of what you do.
