Quran 2:49 — The Heifer (Al-Baqarah)

وَإِذ نَجَّينٰكُم مِن ءالِ فِرعَونَ يَسومونَكُم سوءَ العَذابِ يُذَبِّحونَ أَبناءَكُم وَيَستَحيونَ نِساءَكُم ۚ وَفى ذٰلِكُم بَلاءٌ مِن رَبِّكُم عَظيمٌ

Recall that we saved you from Pharaoh's people who inflicted upon you the worst persecution, slaying your sons and sparing your daughters. That was an exacting test from your Lord.

[2:48] Beware of the day when no soul can avail another soul, no intercession will be accepted, no ransom can be paid, nor can anyone be helped.

[2:50] Recall that we parted the sea for you; we saved you and drowned Pharaoh's people before your eyes.
