Hanifism is a word used to describe the Messianic religion of certain Fertile Crescent Baptists (Sabians) sometimes referred to as Abrahamists or Hanafite Christians.
Although they simply called themselves "believers", they are best distinguished by their perculiar use of the slur "Hanifian" (Apostatian) to refer to Abraham to give hope to people from Apostate backgrounds thereby sanitising the insult which was regularly applied to them as Acephali by the Christian Hierarchies which they rejected.
These Baptists left plenty of rock inscriptions in Arabi Mubeen but most of their doctrine comes from a certain 7th century Persian Charismatic called Gabriel of Sinjar. Gabriel claimed no ability in the Lisan Arabi Mubeen of his ecclesiastical poems for Sabi Apostles being not his own compositions but allegedly from Christ's Angel through the Spiritual gift of tongues by the power of the Father's name. These Baptists believed the Father's name had become flesh as the Messiah Jesus Mary's Son Rasul of the Father's physical Appearance (Divine Temple) which these Baptists called Mahmad (not to be confused with the Arabian Nabi) and so were also referred to as tribes of Mahmad.
Mahmad's Baptists did not distinguish themselves much from their covenanted allies who they called Musulman despite regarding them as most prone to hypocrisy and disbelief. Next, they considered the closest to their Association (Quraysh) to be the Nestorians (who say Allah's Rasul is a partnership between the divine and its creation) but did not take them as allies nor the Judaizers (who oppose ascribing any kind of uncommon divinity to Allah's Rasul), whom they called Judases and regarded as traitors although they did accept converts from the latter.
Mahmad's Baptists did not come into focus until an influential person (probably) Iyyas ibn Qabisa of Tayyaye, who was Khosrow II's Nestorian Client in AlHira over the Lakhmid joined their movement as a Mursal being a Nabi of the Rasul (Eucharist). This leader was married to a Nestorian called Khadijah by her cousin a Nestorian Priest called Waraqah. As leader in Al-Hira over the Lakhmid he could have been called Melkhamed. By the time Sebeos had heard of him many Arabs had already begun to promote him as their Messiah and changed his title from Melkhamed to Mohamed. But to do so they had to diminish the importance of the Christian Messiah and in doing so a new religion was born.
Long before all that would happen, the Lakhmid ruler was ousted from Al-Hira by Pasigs in 617AD. He petitioned the King of Abyssinia for some land which he was granted on a floodplain called Makah in the Hejaz and joined the Heraclian revolutionaries.
When Heraclius defeated Khosrow, Iyyas presenting himself as the last Lakhmid joined the free Arab state of Free Medina and a revenge attack against the traitors of Al-Hira.
But until his death he was still just one of many Nabis of the Sabian faith who had learned Gabriel's Ecclesiastical poetry.
After the Byzantine Victory of 622, these Baptists did present their faith to Heraclius as the Hadiths claim but there was no leader by the name of Muhammad to be heard of according to the Byzantine version of the story. In fact, the belief presented was Monophysitsm and the presenter was called Paulic (its adherents came to be called Paulician by the Byzantines ever since). But Heraclius decided he knew better and came up with his own idea which he called Monoenergism.
At first it seems no one really knew what Heraclius meant. Some Monophysites (especially modalists) accepted his terminology. Others were more cautious.
Khosrow II was overthrown in 628 and was replaced by the rather Monophysite Byzantine Emperor Maurice's grandson Kavad II in Old Medina who appointed Heraclius regent over his son when he died.
Understanding the chronology of what happened next is essential.
It seems first that the Ghassanid Monophysite Church entered a brief union with Heraclius.
But then the Nestorians were allowed to establish their own Catholicos again greatly upsetting the Monophysites. Many would have joined the Acephali in protest against the Ghassanid Patriarch at this time.
Heraclius proclaimed himself "Basileus" in 629 the first Greek since the Seleucids to be Persia's King of Kings greatly upsetting the Pahlavis.
The Monophysite Church immediately broke communion with Heraclius and established a Maphrian of all the East to oppose the Nestorian Catholicos. This may have been to appease their congregations who were no doubt furious about being united to the Nestorians.
At the same time the Pahlavis had different ideas and rejected Heraclius's regency over Kavodh's young son Ardashir whom they established on the throne instead triggering the chain of events which eoon led to Arab supremacy in the region. There was nothing supernatural about it.
Heraclius's responded by instigating a civil war between the Parsigs and Pahlavis while the Arabs no doubt broke out their popcorn to sit back and watch the show.
Heraclius sent the Zoroastrian Shahrbaraz to kill the young Prince Ardashir and crucify his Christian supporters. Shahrbaraz established himself on the throne in 630 but was quickly replaced by the Monophysite Christian Borandokht who was in turn dethroned by Parsing Shapur followed by her own half-sister the Zoroastrian Azarmidokht. Azarmidokht was opposed by the Pahlavi Farrukh whom she executed then Farrukh's son Rostam who executed her and restored Borandokht to the throne in 631. But the Parsigs did not give up and had her strangled in 632. A truce between the Pasigs and Pahlavis was reached and Yazdegard was established on the throne in 632 as a compromise between the two parties. His daughter Shahrbonu was wed to Iyyas's son in law Ali who ruled from Al-Hira after him.
According to our Thesis, Ali represented Hanifism as Islam had not yet been invented. According to our theory it was Abu Bakr, and Umar then Uthman who laid the ground work for the establishment of the Book of the Arabs and the Religion of the Arabs created under Abdul Malik.
This theory explains how Pope Martin could have been charged with granting the Saracens their "Tome" as it would not have been vastly different from the Dyoenergists at this point who were all working together against the anti-Dyoenergism of the 7th century Byzantine Emperors.
The "Tome" in question is the original Syro-Aramaic one that Ali offered to his predecessors but which they rejected in favour of the partly goat-eaten Hafsa Mushaf. Ali's is also the same version which was defended by ibn Mansur and his supporters whom Uthman had killed.
