وَأَصۡبَحَ فُؤَادُ أُمِّ مُوسَىٰ فَٰرِغًاۖ إِن كَادَتۡ لَتُبۡدِي بِهِۦ لَوۡلَآ أَن رَّبَطۡنَا عَلَىٰ قَلۡبِهَا لِتَكُونَ مِنَ ٱلۡمُؤۡمِنِينَ

Wa qaalatim ra atu Fir'awna qurratu 'aynil lee wa lak; laa taqtuloohu 'asaaa aiyanfa'anaa aw nattakhizahoo waladanw wa hum laa yash'uroon

But there came to be a void in the heart of the mother of Moses: She was going almost to disclose his (case), had We not strengthened her heart (with faith), so that she might remain a (firm) believer.

— Al-Qasas (ٱلْقَصَص), 28:10
