النساۤء — An-Nisa' Ayat 48
اِنَّ اللّٰهَ لَا يَغْفِرُ اَنْ يُّشْرَكَ بِهٖ وَيَغْفِرُ مَا دُوْنَ ذٰلِكَ لِمَنْ يَّشَاۤءُ ۚ وَمَنْ يُّشْرِكْ بِاللّٰهِ فَقَدِ افْتَرٰٓى اِثْمًا عَظِيْمًا
Innallāha lā yagfiru ay yusyraka bihī wa yagfiru mā dūna żālika limay yasyā'(u), wa may yusyrik billāhi fa qadiftarā iṡman ‘aẓīmā(n).
"Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills. And he who associates others with Allah has certainly fabricated a tremendous sin."
