Am lahum shurakaaa'u shara'oo lahum minad deeni maa lam yaazam bihil laah; wa law laa kalimatul fasli laqudiya bainahum; wa innaz zaalimeena lahum 'azaabun aleem
Or have they partners [i.e., other deities] who have ordained for them a religion to which Allah has not consented? But if not for the decisive word, it would have been concluded between them. And indeed, the wrongdoers will have a painful punishment.
1 Mufti Taqi Usmani
Is it that they have associate-gods who have prescribed for them a religion that is not sanctioned by Allah? Had it not been for a decisive word, the matter would have been decided between them (here in this world). And of course, for the wrongdoers there is a painful punishment (in the Hereafter).
