Surah 2 : Ayah 49

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

And [remember] when We saved you from Pharaoh’s people, who were inflicting dreadful torment upon you: slaughtering your sons and sparing your women. That was a great trial from your Lord.
