Surah Yusuf — Ayah 89 (12:89)
قَالَ هَلۡ عَلِمۡتُم مَّا فَعَلۡتُم بِيُوسُفَ وَأَخِيهِ إِذۡ أَنتُمۡ جَٰهِلُونَ ٨٩
English translation (Saheeh International)
He said, "Do you know what you did with Joseph and his brother when you were ignorant?"
Brief commentary
When he heard their words he felt compassion towards them, and let them know who he was, asking them if they knew what they did to Joseph and his full brother when they were ignorant of the consequences of what they did to them.
