It is connected to other works and is considered a part of a series demolishing the idol of Muawiya (who demolished the caliphate and tens of thousands of companions and even more regular Muslims to establish monarchy that its effects are oppressing us to this day monarchy after monarchy and dictatorship after another as if it's OK or islamic, etc)
Samura was an enforcer for for Ziyad brother of Muawiyah who was installed governor in Basra and Kufa in Iraq by Muawiya and hr approved of Samura and his actions of mass murder of Muslims and any who dared to return the caliphate or at least get shura back as in their authority in their lands i consultation. (BTW alhasan albasry was known to believe whoever narrated to him). This small research book opens with authenticating(rigorously) the hadith of the Prophet pbuh by Abu Hurairah : That the Prophet, peace be upon him, said to ten of his companions in a house, "The last of you to die will be in the fire". In them is the brow of a soldier. And that , " Samra was the last of them to die . "
And that this hadith was definitely said by Abu Hurairah (by eight different source narrations as in the Narration has 7 other affirming narrations) and he was absolutely terrified that he would be the last to die and it be applied on him.
Samura even sold alcohol not caring about it being haram and a cursed thing to do so when Caliph Omar heard of it he said May God Fight Samura (which is the title of the research)

(This is just a tiny bit of the research)
TL;DR
Purpose of the work – Part of a larger series that seeks to dismantle the mythologized image of Muʿāwiyah ibn Abī Ṣufyān, whose establishment of hereditary monarchy shattered the original‑consultative (shūrā) model of the early caliphate and set off a chain of dynastic oppression that still haunts the Muslim world.
Key figure: Samura bn Junb – a ruthless enforcer appointed by Ziyād ibn Muʿāwiyah (Muʿāwiyah’s brother) when Muʿāwiyah placed Ziyād as governor of Basra and Kufa.
Samura led mass killings of Muslims who resisted the new monarchical order or tried to restore shūrā.
He openly dealt in ḥarām liquor; when Caliph ʿUmar ibn Al‑Khaṭṭāb learned of this, he reportedly prayed, “May God fight Samura!” (recorded in Muslim 1582a).
Hadith focus: The author rigorously authenticates a prophetic statement transmitted by Abū Hurayrah:
“The last of you to die will be in the fire.”
The narration includes ten companions gathered in a house; among them is a soldier (Samura). The hadith is supported by eight independent chains (seven additional corroborating reports), establishing its soundness (ṣaḥīḥ) that Abu Hurairah definitely narrated it and more.
Abū Hurayrah himself feared being that “last” and the prophecy was later applied specifically to Samura, who indeed became “the last of them to die.”
Overall argument: By proving the authenticity of the hadith and documenting Samura’s brutal actions under Muʿāwiyah’s regime, the research shows how the early caliphate’s ideals were subverted by a nascent monarchy. It frames Samura as a concrete example of the tyranny inaugurated by Muʿāwiyah—an oppression that has been repeated through successive monarchies and dictatorships, falsely presented as Islamic. The work therefore contributes to the broader project of exposing and rejecting that legacy.
