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

And the heart of Musa’s mother was free (from anxiety) she would have almost disclosed it had We not strengthened her heart so that she might be of the believers.
