This is because they defied and disobeyed Allah and His Messenger. And whoever defies and disobeys Allah and His Messenger, then verily, Allah is Severe in punishment.
Hayo ni kwa sababu wamemuasi Mwenyezi Mungu na Mtume wake. Na mwenye kumuasi Mwenyezi Mungu na Mtume wake basi Mwenyezi Mungu ni Mkali wa kuadhibu.
