It was asked on a previous thread (*) whether Surah 2:106 solves the problem of the missing verse on stoning. The short answer is, it doesn’t. For a slightly longer answer, see below (For those who need the back story on this issue, as well as more detailed treatments of the problems this poses for Muslims, see here)
Here is how Surah 2:106 reads in various translations:
“None of Our revelations
Do We abrogate
Or cause to be forgotten,
But We substitute
Something better or similar:
Knowest thou not that Allah
Hath power over all things?” (Yusuf Ali)
Such of our revelations as We
abrogate or cause to be forgotten,
We bring (in place) one better or the like
thereof. Knowest thou not that Allah is
able to do all things? (Pickthall)
Whatever a Verse (revelation) do
We abrogate or cause to be forgotten,
We bring a better one or similar to it.
Know you not that Allah is Able to do all things? (Hilali)
One problem with this would be that Muhammad never said anything to abrogate the verse on stoning, as is proven by the fact that it was only discovered to be missing from the Qur'an by Umar after the time of Muhammad’s death, and neither was it caused to be forgotten, as is once again demonstrated in the case of Umar. If Umar was nonplussed by the fact that the verse was not to be found in the Qur’an, then according to the testimony of Umar it was never abrogated. If Umar remembered the verse in order to make this observation, then the verse was not forgotten.
A second problem is that Surah 2:106 says that any verse/reveation that is abrogated or caused to be forgotten will be replaced by Allah with something better or similar. Once again this runs aground on the fact that Muhammad was dead at the time the verse on stoning was discovered to be missing. In other words, Muhammad was not around to replace the verse with another one.
In light of this, it is surely ironic that Muslims so often accuse the Jews of removing things from the Torah, such as the command to stone adulterers, and anyone familiar with Muslim commentators knows just how often this example comes up, when the command to stone adulterers is still there in the Torah to this day but is nowhere to be found in the Qur’an.
This is a prime example of the proverb, "Those who live in glass houses should not throw stones". Surely God catches the wise in their craftiness. (Job 5:14)
