Believing the Qur'an was simply a hodgepodge of Jewish and Christian texts, Western scholarship continued to transmit this alleged historical contradiction until recent times, where a balanced and fair look at the relevant texts shows no such anachronism exists.  Though descriptions such as ‘Children of Adam’, ‘Children of Israel’, ‘mother of’ ‘brother of’, ‘sister of’, ‘son of’, etc., may presuppose direct physical consanguinity, they cannot in all instances be understood as such, without imposing a patently absurd, nonsensical understanding of the text.
Figure 2 also gives an idea of what is probable and what is impossible. For example, 2σ accounts for 95% "confidence" concerning the data. Making it 3σ only increases the "confidence" to about 99% - a mere 4% increase that adds a measurement error σ on either side of the mean and extending the range of probable calendar dates. Physically, this increase in 4% "confidence" does not commensurate with an addition of measurement error σ, contrary to case of increase from 1σ (68% "confidence") to 2σ (95% "confidence").
A recent study has argued that the Quran we have today is exactly the same as the one compiled by 'Ali ibn Abi-Talib, and that the reading of Hafs from his teacher 'Asim to be the unaltered reading of 'Ali. This is because 'Asim's teacher, Abu 'Abd al-Rahman al-Sulami, had learnt the Quran from 'Ali. Furthermore, Hafs was a Companion of Imam Ja'far al-Sadiq and it is claimed that the latter had inherited 'Ali's Master Copy of the Quran. The study provides a case that it was 'Ali's Master Copy which formed the basis of the 'Uthmanic canon. As for the reading of Hafs, the study presents evidence that the latter had learnt the Quran from two sources: 'Asim who was his main teacher, and Imam Ja'far al-Sadiq who provided him with a corrective of 'Asim's reading. If future research can validate these preliminary findings, then this could very well mean that the reading of Hafs from Asim is the de facto reading of 'Ali which he inherited from the Prophet till the very last dot."
