AL QASHASH — Ayat 10
وَأَصْبَحَ فُؤَادُ أُمِّ مُوسَى فَارِغًا إِن كَادَتْ لَتُبْدِي بِهِ لَوْلَا أَن رَّبَطْنَا عَلَى قَلْبِهَا لِتَكُونَ مِنَ الْمُؤْمِنِينَ
And the heart of Moses' mother became empty [of all else]. She was about to disclose [the matter concerning] him had We not bound fast her heart that she would be of the believers.
Tafsir Ibnu Katsir
وَأَصْبَحَ فُؤَادُ أُمِّ مُوسَى فَارِغاً إِن كَادَتْ لَتُبْدِى بِهِ لَوْلا أَن رَّبَطْنَا عَلَى قَلْبِهَا لِتَكُونَ مِنَ الْمُؤْمِنِينَ - وَقَالَتْ لأُخْتِهِ قُصِّيهِ فَبَصُرَتْ بِهِ عَن جُنُبٍ وَهُمْ لاَ يَشْعُرُونَ - وَحَرَّمْنَا عَلَيْهِ الْمَرَاضِعَ مِن قَبْلُ فَقَالَتْ هَلْ أَدُلُّكُمْ عَلَى أَهْلِ بَيْتٍ يَكْفُلُونَهُ لَكُمْ وَهُمْ لَهُ نَـصِحُونَ - فَرَدَدْنَـهُ إِلَى أُمِّهِ كَىْ تَقَرَّ عَيْنُهَا وَلاَ تَحْزَنَ وَلِتَعْلَمَ أَنَّ وَعْدَ اللَّهِ حَقٌّ وَلَـكِنَّ أَكْثَرَهُمْ لاَ يَعْلَمُونَ
10. And the heart of the mother of Musa became empty. She was very near to disclose his (case), had We not strengthened her heart, so that she might remain as one of the believers. 11. And she said to his sister: â€Follow him.'' So she watched him from a far place (secretly), while they perceived not. 12. And We had already forbidden foster suckling mothers for him, until she said: â€Shall I direct you to a household who will rear him for you, and look after him in a good manner'' 13. So We restored him to his mother, that her eye might be comforted, and that she might not grieve, and that she might know that the promise of Allah is true. But most of them know not. Allah tells us how, when her child was lost in the river, the heart of Musa's mother became empty, i.e., she could not think of any matter in this world except Musa. This was the view of Ibn `Abbas, Mujahid, `Ikrimah, Sa`id bin Jubayr, Abu `Ubaydah, Ad-Dahhak, Al-Hasan Al-Basri, Qatadah and others.
