Surah Az-Zukhruf — Ayah 56 (43:56)
فَجَعَلۡنَٰهُمۡ سَلَفٗا وَمَثَلٗا لِّلۡأٓخِرِينَ ٥٦
English translation (Saheeh International)
And We made them a precedent and an example for the later peoples.
Brief commentary
So I made Pharaoh and his people an example for those who did actions like theirs, that they would perish just like they did. I also made them a lesson for those who take heed; so that they do not do the same actions as theirs and are then afflicted with whatever came upon them.
