2. Bakara Suresi 233. ayet Taqi Usmani

Mothers (should) suckle their children for two full years, for one who wants to complete the (period of) suckling. It is the obligation of the one to whom the child belongs that he provides food and clothing for them (the mothers) with fairness. Nobody is obligated beyond his capacity. No mother shall be made to suffer on account of her child, nor the man to whom the child belongs, on account of his child. Likewise responsibility (of suckling) lies on the (one who may become an) heir (of the child). Now, if they want to wean, with mutual consent and consultation, there is no sin on them. And If you want to get your children suckled (by a wet-nurse), there is no sin on you when you pay off what you are to give with fairness, and fear Allah, and be assured that Allah is watchful of what you do.

وَالْوَالِدَاتُ يُرْضِعْنَ اَوْلَادَهُنَّ حَوْلَيْنِ كَامِلَيْنِ لِمَنْ اَرَادَ اَنْ يُـتِمَّ الرَّضَاعَةَۜ وَعَلَى الْمَوْلُودِ لَهُ رِزْقُهُنَّ وَكِسْوَتُهُنَّ بِالْمَعْرُوفِۜ لَا تُكَلَّفُ نَفْسٌ اِلَّا وُسْعَهَاۚ لَا تُضَٓارَّ وَالِدَةٌ بِوَلَدِهَا وَلَا مَوْلُودٌ لَهُ بِوَلَدِه۪ وَعَلَى الْوَارِثِ مِثْلُ ذٰلِكَۚ فَاِنْ اَرَادَا فِصَالاً عَنْ تَرَاضٍ مِنْهُمَا وَتَشَاوُرٍ فَلَا جُنَاحَ عَلَيْهِمَاۜ وَاِنْ اَرَدْتُمْ اَنْ تَسْتَرْضِعُٓوا اَوْلَادَكُمْ فَلَا جُنَاحَ عَلَيْكُمْ اِذَا سَلَّمْتُمْ مَٓا اٰتَيْتُمْ بِالْمَعْرُوفِۜ وَاتَّقُوا اللّٰهَ وَاعْلَمُٓوا اَنَّ اللّٰهَ بِمَا تَعْمَلُونَ بَص۪يرٌ
