فَلَا تَدْعُ مَعَ اللَّهِ إِلَهًا آخَرَ فَتَكُونَ مِنَ الْمُعَذَّبِينَ
[26:213]
So call not upon another god with Allah, lest you be of those who are punished.
So call not on any other god with Allah, or thou wilt be among those under the Penalty.
Therefor invoke not with Allah another god, lest thou be one of the doomed.
