Qaf - 50:28

قَالَ لَا تَخْتَصِمُوا لَدَيَّ وَقَدْ قَدَّمْتُ إِلَيْكُم بِالْوَعِيدِ
[50:28]
He will say: Do not quarrel in My presence, and indeed I gave you the threatening beforehand:
He will say: "Dispute not with each other in My Presence: I had already in advance sent you Warning.
He saith: Contend not in My presence, when I had already proffered unto you the warning.
