Sura al-Aʿrāf 7:141

وَإِذْ أَنجَيْنَٰكُم مِّنْ ءَالِ فِرْعَوْنَ يَسُومُونَكُمْ سُوٓءَ ٱلْعَذَابِ يُقَتِّلُونَ أَبْنَآءَكُمْ وَيَسْتَحْيُونَ نِسَآءَكُمْ وَفِى ذَٰلِكُم بَلَآءٌ مِّن رَّبِّكُمْ عَظِيمٌ

wa-idh anjaynākum min āli firʿawna yasūmūnakum suʾa l-ʿadhābi yuqattilūna abnāʾakum wa-yastaḥyūna nisāʾakum wa-fī dhālikum balāʾun min rabbikum ʿaẓīmun

And remember We rescued you from Pharaoh's people, who afflicted you with the worst of penalties, who slew your male children and saved alive your females: in that was a momentous trial from your Lord.
