al-Ḍaḥḥāk and others said: “The heart of Moses’ mother became vacant” —that is, empty of every worldly concern except Moses himself. “She was on the verge of revealing him,” meaning she was about to disclose his affair and ask about him openly, “had We not bound fast her heart,” that is, had We not made her patient and steadfast, “so that she might be among the believers.”
She then said to his sister—her eldest daughter—“Follow him,” meaning: trace his footsteps and bring me news of him. “So she watched him from a distance.” Mujāhid said: from afar; while Qatādah said: she kept looking at him as though she did not want him, hence the words, “while they were unaware.”
Once Moses, peace be upon him, had settled in Pharaoh’s household they tried to feed him at the breast, but he would accept no nurse and took no food. They were at a loss and did everything they could to nourish him, yet he refused, just as the Most High said: “We had already forbidden him wet nurses beforehand” (al-Qaṣaṣ 12). They therefore sent him with midwives and women to the marketplace, hoping to find someone whose milk he would take. While they stood there with the people gathered around, his sister saw him but did not show that she recognized him. Instead she said, “Shall I direct you to a household who will look after him for you and will be sincere toward him?” (al-Qaṣaṣ 12).
Ibn ʿAbbās said: When she said that, they asked her, “How do you know they will be kind and compassionate toward him?” She replied, “Out of desire to be connected to the king (2) and in hope of his favor.” So they released her and went with her to the house. His mother took him; the moment she suckled him he latched on to her breast and began to drink, whereupon they rejoiced greatly. A messenger hurried to Āsiyah to inform her, and she summoned the mother, offering to keep her with her and treat her well. The mother declined, saying, “I have a husband and children, and I cannot manage this unless you send him with me.” Āsiyah agreed, fixed her a stipend, and allotted for her food, clothing (3), and gifts. She returned home carrying him (4), and Allah reunited the two of them.
Allah the Exalted said: “Thus We returned him to his mother so that her eye might be comforted, that she might not grieve, and so that she might know that the promise of Allah is true; yet most of them do not know” (al-Qaṣaṣ 13)—just as We promised to restore him and to make him a messenger. His return, therefore, is proof of the truth of the glad tidings of his prophethood, “but most of them do not know.”
Allah reminded Moses of this favor on the night He spoke to him (5), saying:
“And indeed We bestowed Our favor upon you another time
when We inspired to your mother what was inspired:
‘Place him in the chest, then cast it into the river;
the river will throw him onto the bank;
an enemy to Me and an enemy to him will take him.’
I cast upon you love from Me,
so that you would be reared under My watchful eye” (Ṭā Hā 20:37–39).
Qatādah and several other early scholars (7) said: meaning that you would be fed, cared for, and nurtured under My protection.
