﴿ قَالَ لَا تَخْتَصِمُوا۟ لَدَىَّ وَقَدْ قَدَّمْتُ إِلَيْكُم بِٱلْوَعِيدِ ﴾

“[And] He will say: “Contend not before Me, [O you sinners,] for I gave you a forewarning [of this Day of Reckoning].”

لَا تَخْتَصِمُوا لَدَيَّ وَقَدْ قَدَّمْتُ إِلَيْكُم بِالْوَعِيدِ ("Do not quarrel before Me, while I had sent to you My threat well in advance.... 50:28) It means: "I have given you sufficient proof by the words of the past Messengers, and I have sent down the Divine Books; the evidences, signs and proofs have thus been established against you; your flimsy excuses, arguments and disputes will not work today.'
