Translation:

71. Yet they worship besides Allah things for which no authority has been sent down to them and of which they have (really) no knowledge: for those that do wrong there is no helper.

Notes (Tafseer)

2852. When plain common-sense shows the absurdity of false worship, behind which there is neither knowledge, intelligence, nor authority (quite the contrary), who or what can help the false misguided creatures who dishonour Allah by false worship?
