وَإِذ نَجَّيناكُم مِن آلِ فِرعَونَ يَسومونَكُم سوءَ العَذابِ يُذَبِّحونَ أَبناءَكُم وَيَستَحيونَ نِساءَكُم ۚ وَفي ذٰلِكُم بَلاءٌ مِن رَبِّكُم عَظيمٌ

And [recall] when We saved 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.
