Another issue often raised about the Qur’anic preservation is about the total number of verses in Surah Ahzab i.e. the 33rd chapter of the Holy Qur’an. In the established Qur’anic text and in all manuscripts ever known in history the total number of verses has been 73 but few narrations give a notion contrary to this.
1- The narrations on this account are found in many collections like that of Ahmad, Hakim, Baihaqi, Ibn Hibban, Nasai [his Sunan al-Kubra], Tiyalsi and others. And from there it has been quoted by Ibn Kathir, Qurtubi and in Kanzul Ummal etc.
