Surat Al Anfal: (13-14)

{ذَلِكَ بِأَنَّهُمْ شَآقُّواْ اللّهَ وَرَسُولَهُ وَمَن يُشَاقِقِ اللّهَ وَرَسُولَهُ فَإِنَّ اللّهَ شَدِيدُ الْعِقَابِ} [الأنفال: 13]

13- The disbelievers deserved that punishment because they had disobeyed the commands of Allah, left His Shari`ah, fought the Prophet (peace be upon him) and joined the lines of his enemy. Whoever disobeys the commands of Allah and His Messenger shall be punished severely.

{ذَلِكُمْ فَذُوقُوهُ وَأَنَّ لِلْكَافِرِينَ عَذَابَ النَّارِ} [الأنفال: 14]

14- So, taste that torture, exemplary punishment, defeat, and loss, and let it be known that the disbelievers shall have a prepared torment in Hell that is more than the worldly punishment.
