Quran 20:109 from Surah Taa-Haa on Divine Marvels.
يَوۡمَئِذٖ لَّا تَنفَعُ ٱلشَّفَٰعَةُ إِلَّا مَنۡ أَذِنَ لَهُ ٱلرَّحۡمَٰنُ وَرَضِيَ لَهُۥ قَوۡلٗا
English translation: (On) that Day not will benefit the intercession except (to) whom has given permission [to him] the Most Gracious and He has accepted for him a word
Transliteration: yawma-idhin la tanfa'u al-shafa'atu illa man adhina lahu al-rahmanu waradiya lahu qawlan
