Translation:

73. O men! Here is a parable set forth! Listen to it! Those on whom besides Allah ye call cannot create (even) a fly if they all met together for the purpose! And if the fly should snatch away anything from them they would have no power to release it from the fly: feeble are those who petition and those whom they petition!

Notes (Tafseer)

2855. Both idols and their worshippers are poor, foolish, feeble creatures!
