from the sermons of Imam Ali(pace be upon him ):sermon115

About troubles which would arise and the Day of Judgment

Allah deputed him (the Prophet (P.B.U.H. and His Household)  ) as a caller towards Truth and a witness over the creatures. The Prophet (P.B.U.H. and His Household)  conveyed the messages of Allah without being lazy and without any short-coming, and he fought His enemies in the cause of Allah without being languid and without pleading excuses. He is the foremost of all who practice piety and the power of perception of all those who achieve guidance.

A portion of the same sermon, complaining about his men:

If you know what I know of the unknown that is kept wrapped up from you certainly you would have gone out into the open weeping over your deeds and beating yourselves in grief. You would have abandoned your properties without any guard for it or any substitute over it. Everyone would then have cared for his own self without paying attention to anyone else. But you have forgotten what was recalled to you and felt safe from what you had been warned. Consequently, your ideas went astray and your affairs were dispersed.

I do long that Allah may cause separation between you and me and given me those who have a better right to be with me than you. By Allah, they are people of blissful ideas, enduring wisdom and true speech. They keep aloof from revolt. They trod forward on the path (of Allah) and ran on the high road. Consequently, they achieved the everlasting next life and easeful honors.

Beware! by Allah, a tall lad of swinging gait from Banu Thaqif would be placed over you. He would eat away your vegetation and melt your fat. So, O Aba Wadhahah, is that all?

Sayyid ar-Radhi says the following: A al-Wadhahah means A al-khunfusa (dung-beetle). In this sentence Imam Ali ibn Abu Talib (A.S) has referred to al-Hajjai ibn Yusuf ath-Thaqafi and he had an incident with A al-Khunfusa’, which need not be related here.1

The detail of this incident is that one day al-Hajjaj stood up for saying prayers when al-khunfusa’ advanced towards him. Al-Hajjaj held out his hand to stop him but he bit him whereby his hand got swollen and eventually he died of it.

Ibn Abul-Hadid has written that A al-Wadhahah means the dung that remains sticking to the tail of an animal, and this surname is intended to disgrace him.
