Surah Al-Baqarah, Verse 49

وَإِذۡ نَجَّيۡنَٰكُم مِّنۡ ءَالِ فِرۡعَوۡنَ يَسُومُونَكُمۡ سُوٓءَ ٱلۡعَذَابِ يُذَبِّحُونَ أَبۡنَآءَكُمۡ وَيَسۡتَحۡيُونَ نِسَآءَكُمۡۚ وَفِي ذَٰلِكُم بَلَآءٞ مِّن رَّبِّكُمۡ عَظِيمٞ٤٩

wa-idh najjaynākum min āli fir'ʿawna yasūmūnakum sūa l-ʿadhābi yudhabbiḥūna abnāakum wayastaḥyūna nisāakum wafī dhālikum balāon min rabbikum ʿaẓīmun

And [recall] when We saved you [i.e., your forefathers] from the people of Pharaoh, who afflicted you with the worst torment, slaughtering your [newborn] sons and keeping your females alive. And in that was a great trial from your Lord.
