Al-Hijr - ১৫:৯৬

الَّذِينَ يَجْعَلُونَ مَعَ اللّهِ إِلـهًا آخَرَ فَسَوْفَ يَعْمَلُونَ
[15:96]
Those who set up another god with Allah; so they shall soon know.
Those who adopt, with Allah, another god: but soon will they come to know.
Who set some other god along with Allah. But they will come to know.
