[Pooya/Ali Commentary 77:17] As said in verse 13, on the day of judgement good will be completely separated from evil. Those who chose falsehood and belied truth will be the losers, therefore "Woe on that day unto the beliers!" has been repeated as a march of punishment unto the disbelievers. Refer to the commentary of Hajj: 5 for verses 20 to 23. Refer to the commentary of Nahl: 15 for verses 25 to 27. Refer to the commentary of Nur: 24 for verses 35 and 36. Aqa Mahdi Puya says: The beliers were given plain and clear guidance but they refused to accept it.
