And those they invoke besides Him do not possess [power of] intercession; but only those who testify to the truth [can benefit], and they know.
The Saheeh International Quran Translation
وَلَا يَمْلِكُ ٱلَّذِينَ يَدْعُونَ مِن دُونِهِ ٱلشَّفَٰعَةَ إِلَّا مَن شَهِدَ بِٱلْحَقِّ وَهُمْ يَعْلَمُونَAnd those they invoke besides Him do not possess [power of] intercession; but only those who testify to the truth [can benefit], and they know.
