Islam Critiqued finds Abraham's successors; the hanif remnants?

In answer to the video "Abraham and the Kaaba: From Borrowed Stories to Sacred Scripture"

The history records this legacy of Ibrahim and Ismail, especially with the hanifs, a term used first and foremost as an uncompromising opposition to polytheism 10:105,22:30-1,98:5. It also describes mankind's original predisposition to uprightness 30:30. Hanif stems from H-N-F, which is lexically very interesting. It means the foot that is tilted inwards so that the sole is exposed. In the highly metaphorical language of the Arabs, it became used for the one that exposes his inner self, his secrets, has nothing to hide due to his uprighteness, rectitude. The opposite of hanaf is janaf, indicating the outward inclination of the feet. It is used to imply crookedness of intent in 2:182. As to hanaf, a
water tap is called hanafiya, from the same root, because of the straight manner that water comes out of it. A person born with a condition that made both feet point to eachother when walking was referred to as rajulun "ahnaf" because that person walks in a straight manner and can only change direction with difficulty. The common denominator to all these subtle meanings, is straightness, rectitude.
Because to the pre-islamic Arabs, their forefather Ibrahim's spiritual way was independant of all belief systems of the time, be it the loathsome distortions of Judaism and Christianity or Idolatry, it was considered as close to man's original upright predisposition as one can be, and thus the word became associated with those seeking to emulate him 3:67,6:161. They were a minority that tried preserving the original monotheism of Ibrahim. They neither wanted to belong to Christianity with its notion of dying god incarnate nor to Judaism and its ethno centered deity.

These hanif remnants and keepers of the way of Ibrahim, like their forefather, severed their ties with their community and kinsfolk whom they found walking an erroneous path 

43:26-9"And when Ibrahim said to his father and his people: Surely I am clear of what you worship, Save Him Who created me, for surely He will guide me. And he made it a word to continue in his posterity that they may return.".

These small groups of Meccan men and women detested the use of the Kaaba by the polytheists and kept their practice of religion monotheistic. They affirmed that the Abrahamic legacy had been distorted beyond recognition, whether by the Jews, Christians or Ishmaelites brethren, and these personalities were seeking a return to the pristine religion. The traditions mention their names and how their ways of life would lead them to harassement by the Idol worshipers. They include names like Uthman ibn Huwayrith, Ubaydullah bin Jahsh, Zayd ibn Amr ibn Nawfal Al-Nabighah al Ja'adi etc, as well as Muhammad the orphan whom they all knew and hence couldnt accuse him of change of heart

10:16"I have lived a lifetime among you before it".

Muhammad essentially raised himself, never worshiped the idols, never entertained the idea of doing so in the past 109:1-6. He would retreat away from the pagan environement to contemplate as some of his forefathers did, such as his great grand father the hanif, Hashim ibn Abd al-Manaf. He would remain in such wandering perplexity until his prophetic call came unexpectedly. His firm stance against associating with God and polluting the Kaaba reached its peak then, despite his opponents' demands to compromise his message with their beliefs 68:9.

The Hanif rejected the consumption of meat slaughtered in the name of idols as well as other pagan rituals and abominable practices like the burrying of infants alive, which they openly decried. They performed circumcision and rites that were similar to the Israelite rites of the altar sacrifice even before the coming of Muhammad. Josephus in his Antiquites speaks of the Arabs as Ishmael's descendants, way before the time of Muhammad, almost 500 years, saying they circumcized their children at 13 years old, as was still done in the times of the prophet, to commemorate their forefather Ishmael. 

Uri Rubin (Professor, Tel Aviv University) "The pre-Islamic Abrahamic sacredness of the Kaaba is clearly demonstrated in the belief that Abraham's footprints could be seen on one of its sacred stones. This belief is reflected in the very early verses attributed to Abii Talib in which numerous pre-Islamic places of worship are described in a manner which is totally independent of the phraseology of later Islamic sources. The verse referring to Abraham's' footprints reads "wa-mawtii Ibrahima fi l-sakhri ratbatun 'ala qadamayhi hafiyan ghayra na'ili/By Abraham's footprint in the rock still fresh / with both feet bare, without sandals". Later on, Muslim tradition applied to the stone bearing Abraham's footprints the Quranic epithet "Maqam lbrahim". Even the view that the haram, i.e., the sacred territory of Mecca, was founded by Abraham may be regarded as pre-Islamic in origin. Muhammad b. Habib (d. 245H/859), has recorded in his Munammaq a remarkable report saying that Quraysh once asked Thaqif to become their partners in the Meccan haram, in return for equal partnership of Quraysh in the territory of Wajj which was owned by Thaqif. Thaqif refused saying: "How can you be partners in a land in which our father settled, and dug it out of the rocks with his bare hands, without iron tools. And you have not founded the haram by yourselves. It was Abraham who founded it". In other words, Thaqif maintained that Quraysh had no right to make transactions with the Meccan land due to its Abrahamic sacredness. Later on, Muhammad established the haram of Medina on the model of the Abrahamic haram of Mecca".

There is a reason why virtually every non-Muslim writer that witnessed the rise of Islam, from polemicists the likes of John of Damascus that had every reason to refute Muslim claims, to Sebeos in Armenia and beyond, regardless of precise dating and authorship of the works attributed to various Judeo-Christian elite accross the region, almost all of them refer to the Abrahamic ancestry of Muhammad and the Muslims.

In a short Nestorian chronicle, the Khuzistan Chronicle written around 660, in the section concluding the death of Heraclius, the writer says

"the victory of the sons of Ishmael who overpowered and subdued these two strong empires, came from God."

The chronicler further observes

"Regarding the dome of Abraham, we have been unable to discover what it is except that, because the blessed Abraham grew rich in property and wanted to get away from the envy of the Canaanites, he chose to live in the distant and spacious parts of the desert. Since he lived in tents, he built that place for the worship of God and for the offering of sacrifices. It took its present name from what it had been, since the memory of the place was preserved with the generations of their race. Indeed, it was no new thing for the Arabs to worship there, but goes back to antiquity, to their early days, in that they show honour to the father of the head of their people. Hasor, which scripture calls "head of the kingdoms" (Joshua 11:10), belongs to the Arabs, while Medina is named after Midian, Abraham's fourth son by Qetura; it is also called Yathrib. And Dumat Jandal [belongs to them], and the territory of the Hagaraye, which is rich in water, palm trees and fortified buildings. The territory of Hatta, situated by the sea in the vicinity of the islands of Qatar, is rich in the same way; it is also thickly vegetated with various kinds of plants. The region of Mazon also resembles it; it too lies by the sea and comprises an area of more than 100 parasangs. So [belongs to them] too the territory of Yamama, in the middle of the desert, and the territory of Tawf, and the city of Hira, which was the seat of king Mundar, surnamed the "warrior;" he was sixth in the line of the lshmaelite kings".
