Why do you need me to explain anything? You haven’t even told me who “me” is in the quote which means I’m going to have to go look it up on some fatwa site about adultery to find out who narrated this and WHEN, and read about the removal of the verse about stoning and this confused length about Surat al-Ahzab. .
In Sahih al Bukhari Volume 8, pages 209-210, we read this sermon delivered by Hadhrath Umar during his last Hajj as Khalifa:
“Certainly Allah sent Muhammad with the truth, and revealed to him the Book. One of the revelations which came to him was the verse of stoning. We read it and understood it”.
"The Messenger of God stoned and we stoned after him. I am concerned that if time goes on, someone may say, ‘By God, we do not find the verse of stoning in the Book of God;’ thus, the Muslims will deviate by neglecting a commandment the Almighty revealed."
"Stoning is in the Book of God. It is the right punishment for a person who commits adultery if the required witnesses are available, or there was pregnancy without marriage or adultery is admitted."
Al-Muttaqi 'Ali bin Husam al-Din in his book “Mukhtasar Kanz al-'Ummal” printed on the margin of Imam Ahmad’s Musnad, Volume 2, page 2, in his hadith about chapter 33, said that Ibn Mardawayh reported that
Hudhayfah said:
'Umar said to me ‘How many verses are contained in the chapter of al-Ahzab?’ I said, ‘72 or 73 verses.’** He said it was almost as long as the chapter of the Cow, which contains 287 verses, and in it there was the verse of stoning.**
Suyuti narrates from Hadhrath Ayesha:
“During the life of the Prophet (s), Surah Ahzab was read with 200 verses, when Uthman collected the verses we only found that amount that is found in the current Qur’an”.
Tafseer Durre Manthur Volume 5 page 180, al Itqan Volume 2 page 25
Aal Hafidh Jalaladeen as Suyuti writes:
**
“Hadhrath Umar said at the Saqifa that the Qur’an has 1,027,000 letters”**
Tafseer al Itqan" by as Suyuti, page 88
The present Qur’an has 267,033 letters.
In Sahih Muslim Volume 7 (commentary of al-Nawawi) in the Book of al-Zakah, about the virtue of being satisfied with whatever God gives and about urging people to have that virtue, pages 139-140, reported that Abu al-Aswad reported that his father said:
“Abu Musa al-Ash’ari invited the Qur’an readers of Basra. Three hundred readers responded to his invitation. He told them: You are the readers and the choice of the people of Basra. Recite the Qur’an and do not neglect it. Otherwise, a long time may elapse and your hearts will be hardened as the hearts of those who came before you were hardened.”
"We used to read a chapter from the Qur’an similar to Bara’ah in length and seriousness, but I forgot it. I can remember from that chapter only the following words:
'Should a son of Adam own two valleys full of wealth, he would seek a third valley, and nothing would fill Ibn Adam’s abdomen but the soil.
"'We used to read a chapter similar to Musabbihat and I forgot it. I only remember out of it the following:
“'Oh you who believe, why do you say what you do not do? Thus a testimony will be written on your necks and you will be questioned about it on the Day of Judgment.”
It is obvious that these words which Abu Musa mentioned are not from the Quran. Abu Musa says that two surah’s from the Quran are missing, one of them similar to Bara’ah (the chapter of Bara’ah contains 130 verses).
Muslim reported in the Book of al-Rida’ah (Book of Nursing), part 10, page 29, that 'Ayesha said the following:
“There was in what was revealed in the Qur’an that ten times of nursing known with certainty makes the nursing woman a mother of a nursed child. This number of nursing would make the woman ‘haram’ (forbidden) to the child. Then this verse was replaced by ‘five known nursing’ to make the woman forbidden to the child. The Prophet died while these words were recorded and read in the Qur’an.”
We read Sahih al Bukhari Volume 5 hadith number 86:
Alqama went to Sham and when he entered the mosque, he said, “O Allah! Bless me with a pious companion.” So he sat with Abu Ad-Darda. Abu Ad-Darda’ asked him, “Where are you from?” 'Alqama replied, “From the people of Kufa.” Abu Ad-Darda said, “Isn’t there amongst you the keeper of the secret which nobody else knows, i.e., Hudhaifa?” Alqama said, “Yes.” Then Abu Ad-Darda further said, “Isn’t there amongst you the person whom Allah gave refuge from Satan through the invocation of His Prophet, namely Ammar?” Alqama replied in the affirmative. Abu Ad-Darda said, “Isn’t there amongst you the person who carries the Siwak (or the Secret) (i.e. of the Prophet, namely Abdullah bin Masud)?” Alqama said, “Yes.” Then Abu Ad-Darda asked, "How (Abdullah bin Masud) used to recite the Surah starting with: ‘By the night as it envelops; By the day as it appears in brightness?’ " (92.1-2). Alqama said “And by male and female.” Abu Ad-Darda then said, “These people (of Sham) tried hard to make me accept something other than what I had heard from the Prophet.”
We read in Mustadrak:
Abdullah bin Abbas would read the following verse in Surah Nisa “Fa ma asthathamthathu ba manaan ku” with these words 'la ajal masmee". When he was asked about this he said 'Allah (swt) revealed this verse in this way.
Allamah Dhahabi in his commentary of Mustadrak, confirms that the chain of narrators in this tradition is Sahih. (Mustadrak ma Talkhees Volume 2 page 305).
After all the chain is Sahih and Ibn Abbas is stating that words are missing from the Qur’an.
