Ta-Ha - 20:109

يَوْمَئِذٍ لَّا تَنفَعُ الشَّفَاعَةُ إِلَّا مَنْ أَذِنَ لَهُ الرَّحْمَنُ وَرَضِيَ لَهُ قَوْلًا
[20:109]
On that day shall no intercession avail except of him whom the Beneficent Allah allows and whose word He is pleased with.
On that Day shall no intercession avail except for those for whom permission has been granted by (Allah) Most Gracious and whose word is acceptable to Him.
On that day no intercession availeth save (that of) him unto whom the Beneficent hath given leave and whose word He accepteth.
