Al A’raf Ayah 141

وَإِذْ أَنجَيْنَـٰكُم مِّنْ ءَالِ فِرْعَوْنَ يَسُومُونَكُمْ سُوٓءَ ٱلْعَذَابِ‌ۖ يُقَتِّلُونَ أَبْنَآءَكُمْ وَيَسْتَحْيُونَ نِسَآءَكُمْ‌ۚ وَفِى ذَٲلِكُم بَلَآءٌ مِّن رَّبِّكُمْ عَظِيمٌ ١٤١ And ?remember? when We rescued you from the people of Pharaoh, who afflicted you with dreadful torment—killing your sons and keeping your women. That was a severe test from your Lord.
