How does one respond to those who cast doubt on the compilation of the Noble Qur’an during the era of Abu Bakr Al-Siddiq, citing as evidence the hadith about the loss of a verse from Surat Al-Ahzab and its being found with Khuzaimah ibn Thabit?

The narration mentioned by Zayd ibn Thabit, that he lost a verse from Surah Al-Ahzab when compiling the Mushaf and found it with Khuzaymah ibn Thabit al-Ansari, does not mean that no one else knew this verse; for Zayd himself stated that he used to hear the Messenger of Allah, peace and blessings be upon him, recite it, and many Companions had memorized the Qur’an. Zayd's statement "I lost it" only means that he did not find it written down except with Khuzaymah. Zayd's condition for compiling the Qur’an was that no verse should be affirmed in the Mushaf unless it was confirmed to have been written and recorded during the time of the Prophet, peace and blessings be upon him, with the testimony of trustworthy witnesses, and not relying solely on memorization. This occurred during the time of Abu Bakr Al-Siddiq, not during Uthman's era. The Companions' acceptance of this narration and their consensus on its Qur'anic nature is sufficient proof that it is from the Holy Qur'an.
