And (then) you committed that deed which you committed (i.e., you killed a Copt), and you are one of the ungrateful (you have forgotten our guardianship and favours)
“And you did that deed! (Killed one of Pharaoh’s people)... You are of the ungrateful!”
Sayyed Abbas Sadr-Ameli
And you did that your deed which you did, and you are one of the ungrateful
Al-muntakhab fi tafsir al-Qur'an al-Karim
And you did what you did, -the terrible crime you committed-, and you have impelled yourself to ingratitude and ungratefulness to our grace which abounds in you
