﴿ وَفَعَلْتَ فَعْلَتَكَ ٱلَّتِى فَعَلْتَ وَأَنتَ مِنَ ٱلْكَٰفِرِينَ ﴾

“And yet thou didst commit that [heinous] deed of thine, and [hast thus shown that] thou art one of the ingrate!””

(And thou didst that thy deed which thou didst) and you killed the person that you killed, (and thou wast one of the ingrates) and you are now ungrateful for my kindness,
