The discussion is about power and Mu'awiya's bribing of Amr with land to get him on board. Despite Abu Sulaiman's excuses, the words used by Amr bin Aas "Mu'awiya I have sold my religion at your hands", stand as clear testimony that even he felt that he had abandoned his religion by siding with Mu'awiya, but alas for bin Aas his lust for power was so great that it outweighed his iman.

Power was the name of the game not the enforcement "revenge for Uthman" was the war cry via which Mu'awiya sought to enhance his ambitions. We read in al-Akhbar al-Tiwal page 158 "Dhikr Siffeen" that Amr said to Mu'awiya "Give me Egypt to eat from as long as you are a ruler". Tareekh Abu Fida Volume 2 page 238 "Dhikr Siffeen" likewise states that Amr placed a condition that to join Mu'awiya he would be given the power to govern Egypt.

It is indeed interesting to note how the promise of power and authority was the factor that 'moved' Amr bin Aas over to the noble cause of avenging the blood of Uthman. Power was the name of the game not the enforcement "revenge for Uthman" was the war cry via which Mu'awiya sought to enhance his ambitions. What greater proof of the deviance of Mu'awiya can there be than the admission of his key supporter Amr bin Aas.

We read in in Ta'rikh Kamil Volume 2 page 139 "Dhikr Siffeen" that Amr bin Aas said the following to Mu'awiya: "Avenging Uthman's blood was just an excuse, we are desirous of worldly power, upon hearing this Mu'awiya agreed to hand over Egypt to Amr". Do the defenders of Mu'awiya need to be convinced any further? This is the testimony of one of the key central characters in this episode admitting to Mu'awiya that Uthman's revenge was an excuse, the real motive was just power.

If Mu'awiya disagreed with this assertion then why did he not admonish him and set the record straight?

Mu'awiya's testimony further proves his real motive was power not vengeance for the slain Uthman Advocate of Mu'awiya, Ibn Kathir records two interesting references that further exposes the real reason for Mu'awiya's opposition: In Al Bidayah page 131 Volume 8: Un Sayeed bin Sadeed states that in Nakheela, Mu'awiya read Juma and said this, "I haven't fought with you to fast, pray and give Zakaat go on Hajj, you already do this, I fought to become Leader and Commander you don't like this but I have achieved it".
