Tafsir of Al-Ahzab 33:68

ربنا آتهم ضعفين من العذاب

Our Lord! Give them double torment, means, `for their disbelief and because they mislead us.' Abu Al-Qasim At-Tabarani recorded from Abu Rafi` that among the names of those who fought with Ali, may Allah be pleased with him, was Al-Hajjaj bin `Amr bin Ghaziyah, and he was the one who, when they met, said; "O people of the Ansar! Do you want to say when we meet our Lord:

وقالوا ربنا إنا أطعنا سادتنا وكبراءنا فٲضلونا السبيﻼ

ربنا آتهم ضعفين من العذاب والعنهم لعنا كبيرا

Our Lord! Verily, we obeyed our chiefs and our great ones, and they misled us from the way. Our Lord! Give them double torment and curse them with a mighty curse!''
