Almuntakhab Fi Tafsir Alquran Alkarim

And We had already made him reject and refuse breast feeding from all the women who were available to suckle and nurse a strange child. So conditioned, his sister suggested to Pharaohs household a solution, she said: Shall I tell you of a family who would rear him and take good care of him for you

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(28:12) And We had already forbidden the breasts of the nurses for the child. *14 (On seeing this) the girl said to them, "Shall I tell you of a house whose people will bring him up for you and look after him well?" *15

And We had prevented from him [all] wet nurses before, so she meaning

*14) That is, "The child would not take to any nurse whom the queen would call for suckling him."
*15) This shows that the sister did not go and sit back at home when she found that her brother had reached Pharaoh's palace, but cleverly hung about the palace to watch every new development. Then, when she found that the child was not taking to any nurse, and the queen was anxious to get a nurse who would suit it, the intelligent girl went straight into the palace, and said, "I can tell you the whereabouts of a nurse, who will bring him up with great affection." Here it should be borne in mind that in old days the well-to-do and noble families of these countries generally used to entrust their children to nurses for bringing up. We know that in the time of the Holy Prophet also nurses from the suburbs used to visit Makkah from time to time in order to get infants from the well-to-do families for suckling and nursing on rich wages. The Holy Prophet himself was brought up by Halimah Sa diyah in the desert. The same custom was prevalent in Egypt. that is why the Prophet Moses' sister did not say that she would bring a suitable nurse, but said that she would tell them of a house whose people would take up the responsibility of bringing him up with care and affection.

اور ہم نے بچّے پر پہلے ہی دُودھ پِلانے والیوں کی چھاتیاں حرام کر رکھی تھیں (یہ حالت دیکھ کر) اُس لڑکی نے اُن سے کہا "میں تمہیں ایسے گھر کا پتہ بتاؤں جس کے لوگ اس کی پرورش کا ذمّہ لیں اور خیر خواہی کے ساتھ اسے رکھیں؟"
