Quran 4 : 48
بسم الله الرحمن الرحيم
إِنَّ اللَّهَ لَا يَغْفِرُ أَن يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَٰلِكَ لِمَن يَشَاءُۚ وَمَن يُشْرِكْ بِاللَّهِ فَقَدِ افْتَرَىٰ إِثْمًا عَظِيمًا
BESHAK ALLAH NA BAKSHEGA USKE SATH KUFR KIE JANE KO AUR BAKSH DEGA USSE KAM KO JISE CHAHE AUR JO SHARIK THAHRAE ALLAH KA TO BESHAK USNE BADE GUNAH KI TOHMAT LI.
Surely Allah does not forgive that a partner be ascribed to Him, although He forgives any other sins for whomever He wills. He who associates anyone with Allah in His Divinity has indeed forged a mighty lie and committed an awesome sin.
