وَأَصۡبَحَ فُؤَادُ أُمِّ مُوسَىٰ فَٰرِغًاۖ إِن كَادَتۡ لَتُبۡدِي بِهِۦ لَوۡلَآ أَن رَّبَطۡنَا عَلَىٰ قَلۡبِهَا لِتَكُونَ مِنَ ٱلۡمُؤۡمِنِينَ
Wa asbaha fu'aadu ummi Moosaa faarighan in kaadat latubdee bihee law laaa arrabatnaa 'alaa qalbihaa litakoona minal mu'mineen
English Translation
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
