وَأَصْبَحَ فُؤَادُ أُمِّ مُوسَىٰ فَـٰرِغًا ۖ إِن كَادَتْ لَتُبْدِى بِهِۦ لَوْلَآ أَن رَّبَطْنَا عَلَىٰ قَلْبِهَا لِتَكُونَ مِنَ ٱلْمُؤْمِنِينَ

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.

And the heart of the mother of Mûsâ (Moses) became empty [from every thought, except the thought of Mûsâ (Moses)]. She was very near to disclose his (case, i.e. the child is her son), had We not strengthened her heart (with Faith), so that she might remain as one of the believers.
