They namely mankind will not have the power to intercede save him who has made a covenant with the Compassionate One the covenant being the profession of lā ilāha illā’Llāh wa-lā hawla wa-lā quwwata illā bi’Llāh ‘there is no god but God and there is no power or strength except in God’.
- 19:8787
لَا يَمْلِكُونَ الشَّفَاعَةَ إِلَّا مَنِ اتَّخَذَ عِنْدَ الرَّحْمَٰنِ عَهْدًا
