(Thwaha) 20 : 109
يَوْمَئِذٍ لَا تَنْفَعُ الشَّفَاعَةُ إِلَّا مَنْ أَذِنَ لَهُ الرَّحْمَٰنُ وَرَضِيَ لَهُ قَوْلًا
On that Day, no intercession will be benefited except to the one whom the Impartial has given the Permission and has satisfied his word.
It is told in verse 43: 86: “And those they invoke besides Lord don’t possess the power of intercession, but only those who testify the Truth Adhikr and those who are knowing It”. See explanation 19: 87.
