Taha 20:109

Yawma-ithin la tanfaAAu ashshafaAAatuilla man athina lahu arrahmanuwaradiya lahu qawla

That Day, no intercession will benefit except [that of] one to whom the Most Merciful has given permission and has accepted his word.

That day no intercession will be of any use to anyone, except the one whom the RaHmān (All-Merciful, Allah) has permitted and was pleased with his word.
