يَٰمَعْشَرَ ٱلْجِنِّ وَٱلْإِنسِ أَلَمْ يَأْتِكُمْ رُسُلٌۭ مِّنكُمْ يَقُصُّونَ عَلَيْكُمْ ءَايَٰتِى وَيُنذِرُونَكُمْ لِقَآءَ يَوْمِكُمْ هَٰذَا ۚ قَالُوا۟ شَهِدْنَا عَلَىٰٓ أَنفُسِنَا ۖ وَغَرَّتْهُمُ ٱلْحَيَوٰةُ ٱلدُّنْيَا وَشَهِدُوا۟ عَلَىٰٓ أَنفُسِهِمْ أَنَّهُمْ كَانُوا۟ كَٰفِرِينَ
O ye assembly of the jinn and humankind! Came there not unto you messengers of your own who recounted unto you My tokens and warned you of the meeting of this your Day? They will say: We testify against ourselves. And the life of the world beguiled them. And they testify against themselves that they were disbelievers.
Surah Al-An'aam(6:130)
