Al-Isra' - ১৭:২২

لاَّ تَجْعَل مَعَ اللّهِ إِلَـهًا آخَرَ فَتَقْعُدَ مَذْمُومًا مَّخْذُولاً
[17:22]
Do not associate with Allah any other god, lest you sit down despised, neglected.
Take not with Allah another object of worship; or thou (O man!) wilt sit in disgrace and destitution.
Set not up with Allah any other god (O man) lest thou sit down reproved, forsaken.
