1. 2:233 وَٱلْوَٰلِدَٰتُ يُرْضِعْنَ أَوْلَٰدَهُنَّ حَوْلَيْنِ كَامِلَيْنِ لِمَنْ أَرَادَ أَن يُتِمَّ ٱلرَّضَاعَةَ وَعَلَى ٱلْمَوْلُودِ لَهُۥ رِزْقُهُنَّ وَكِسْوَتُهُنَّ بِٱلْمَعْرُوفِ لَا تُكَلَّفُ نَفْسٌ إِلَّا وُسْعَهَا لَا تُضَآرَّ وَٰلِدَةٌۢ بِوَلَدِهَا وَلَا مَوْلُودٌ لَّهُۥ بِوَلَدِهِۦ وَعَلَى ٱلْوَارِثِ مِثْلُ ذَٰلِكَ فَإِنْ أَرَادَا فِصَالًا عَن تَرَاضٍ مِّنْهُمَا وَتَشَاوُرٍ فَلَا جُنَاحَ عَلَيْهِمَا وَإِنْ أَرَدتُّمْ أَن تَسْتَرْضِعُوٓا۟ أَوْلَٰدَكُمْ فَلَا جُنَاحَ عَلَيْكُمْ إِذَا سَلَّمْتُم مَّآ ءَاتَيْتُم بِٱلْمَعْرُوفِ وَٱتَّقُوا۟ ٱللَّهَ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ بِمَا تَعْمَلُونَ بَصِيرٌ

   And the mothers should suckle their children for two whole years for him who desires to make complete the time of suckling; and their maintenance and their clothing must be-- borne by the father according to usage; no soul shall have imposed upon it a duty but to the extent of its capacity; neither shall a mother be made to suffer harm on account of her child, nor a father on account of his child, and a similar duty (devolves) on the (father's) heir, but if both desire weaning by mutual consent and counsel, there is no blame on them, and if you wish to engage a wet-nurse for your children, there is no blame on you so long as you pay what you promised for according to usage; and be careful of (your duty to) Allah and know that Allah sees what you do.
   

2. 4:23 حُرِّمَتْ عَلَيْكُمْ أُمَّهَٰتُكُمْ وَبَنَاتُكُمْ وَأَخَوَٰتُكُمْ وَعَمَّٰتُكُمْ وَخَٰلَٰتُكُمْ وَبَنَاتُ ٱلْأَخِ وَبَنَاتُ ٱلْأُخْتِ وَأُمَّهَٰتُكُمُ ٱلَّٰتِىٓ أَرْضَعْنَكُمْ وَأَخَوَٰتُكُم مِّنَ ٱلرَّضَٰعَةِ وَأُمَّهَٰتُ نِسَآئِكُمْ وَرَبَٰٓئِبُكُمُ ٱلَّٰتِى فِى حُجُورِكُم مِّن نِّسَآئِكُمُ ٱلَّٰتِى دَخَلْتُم بِهِنَّ فَإِن لَّمْ تَكُونُوا۟ دَخَلْتُم بِهِنَّ فَلَا جُنَاحَ عَلَيْكُمْ وَحَلَٰٓئِلُ أَبْنَآئِكُمُ ٱلَّذِينَ مِنْ أَصْلَٰبِكُمْ وَأَن تَجْمَعُوا۟ بَيْنَ ٱلْأُخْتَيْنِ إِلَّا مَا قَدْ سَلَفَ إِنَّ ٱللَّهَ كَانَ غَفُورًا رَّحِيمًا

   Forbidden to you are your mothers and your daughters and your sisters and your paternal aunts and your maternal aunts and brothers' daughters and sisters' daughters and your mothers that have suckled you and your foster-sisters and mothers of your wives and your step-daughters who are in your guardianship, (born) of your wives to whom you have gone in, but if you have not gone in to them, there is no blame on you (in marrying them), and the wives of your sons who are of your own loins and that you should have two sisters together, except what has already passed; surely Allah is Forgiving, Merciful.
   

3. 22:2 يَوْمَ تَرَوْنَهَا تَذْهَلُ كُلُّ مُرْضِعَةٍ عَمَّآ أَرْضَعَتْ وَتَضَعُ كُلُّ ذَاتِ حَمْلٍ حَمْلَهَا وَتَرَى ٱلنَّاسَ سُكَٰرَىٰ وَمَا هُم بِسُكَٰرَىٰ وَلَٰكِنَّ عَذَابَ ٱللَّهِ شَدِيدٌ

   On the day when you shall see it, every woman giving suck shall quit in confusion what she suckled, and every pregnant woman shall lay down her burden, and you shall see men intoxicated, and they shall not be intoxicated but the chastisement of Allah will be severe.
   

4. 28:7 وَأَوْحَيْنَآ إِلَىٰٓ أُمِّ مُوسَىٰٓ أَنْ أَرْضِعِيهِ فَإِذَا خِفْتِ عَلَيْهِ فَأَلْقِيهِ فِى ٱلْيَمِّ وَلَا تَخَافِى وَلَا تَحْزَنِىٓ إِنَّا رَآدُّوهُ إِلَيْكِ وَجَاعِلُوهُ مِنَ ٱلْمُرْسَلِينَ

   And We revealed to Musa's mothers, saying: Give him suck, then when you fear for him, cast him into the river and do not fear nor grieve; surely We wi!l bring him back to you and make him one of the messengers.
   

5. 28:12 وَحَرَّمْنَا عَلَيْهِ ٱلْمَرَاضِعَ مِن قَبْلُ فَقَالَتْ هَلْ أَدُلُّكُمْ عَلَىٰٓ أَهْلِ بَيْتٍ يَكْفُلُونَهُۥ لَكُمْ وَهُمْ لَهُۥ نَٰصِحُونَ

   And We ordained that he refused to suck any foster mother before, so she said: Shall I point out to you the people of a house who will take care of him for you, and they will be benevolent to him?
   

6. 65:6 أَسْكِنُوهُنَّ مِنْ حَيْثُ سَكَنتُم مِّن وُجْدِكُمْ وَلَا تُضَآرُّوهُنَّ لِتُضَيِّقُوا۟ عَلَيْهِنَّ وَإِن كُنَّ أُو۟لَٰتِ حَمْلٍ فَأَنفِقُوا۟ عَلَيْهِنَّ حَتَّىٰ يَضَعْنَ حَمْلَهُنَّ فَإِنْ أَرْضَعْنَ لَكُمْ فَـَٔاتُوهُنَّ أُجُورَهُنَّ وَأْتَمِرُوا۟ بَيْنَكُم بِمَعْرُوفٍ وَإِن تَعَاسَرْتُمْ فَسَتُرْضِعُ لَهُۥٓ أُخْرَىٰ

   Lodge them where you lodge according to your means, and do not injure them in order that you may straiten them; and if they are pregnant, spend on them until they lay down their burden; then if they suckle for you, give them their recompense and enjoin one another among you to do good; and if you disagree, another (woman) shall suckle for him.
