وَأَنَّهُ أَهْلَكَ عَادًا الْأُولَىٰ (50)
(53:50) that He it is Who destroyed the ancient 'Ad, *45
*45) 'Ad Ula signifies the ancient 'Ad to whom the Prophet Hud (peace be upon him) had been appointed a Prophet. When those people were inflicted with the torment in consequence of denying the Prophet Hud, the believers only escaped the punishment. Their descendants are called `Ad Ukhra, or the latter 'Ad, in history.
