We know that in Bukhari Umar bin Khattab also claimed that the verse of Rajam is missing from the Quran
By the way, What guarantee does our Sunni fellows have that there is no other verse is missing from Quran?
Please read Surah Qayamah (75:16-17)” (Muhammad), do not move your tongue too quickly to recite the Quran. We shall be responsible for its collection and its recitation.”
Allah gives guarantee that “we are reponsible for its recitation and collection” But Bukhari tells us the different story..
