إِنَّ اللّهَ لاَ يَغْفِرُ أَن يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَلِكَ لِمَن يَشَاء وَمَن يُشْرِكْ بِاللّهِ فَقَدِ افْتَرَى إِثْمًا عَظِيمًا
﴿٤٨﴾
سورة النساء
(4/48) Verily, Allah does not forgive to be associated partners with Him. And forgives what is besides that for whomsoever He wills; and whoever associates anything with Allah, he has indeed slandered with a tremendous sin.
Surah An-Nisa
