Hazrat ‘Ali (radhiyallahu ‘anhu) said, “Do not speak anything but good regarding Hazrat ‘Uthmaan (radhiyallahu ‘anhu) and the decision that he made concerning the Qur’aan. By Allah, he took this decision concerning the Qur’aan Majeed with the consensus of the Sahaabah (radhiyallahu ‘anhum).” (Saheeh Bukhaari #4987 and Fathul Baari vol. 9 pg. 16)

From this statement, it is clear that Hazrat ‘Ali (radhiyallahu ‘anhu) loved Hazrat ‘Uthmaan (radhiyallahu ‘anhu) and approved of his decision regarding the compilation of the Qur’aan. Hence, the Qur’aan which Hazrat ‘Ali (radhiyallahu ‘anhu) believed in and recited is the very same Qur’aan which the Ahl-us-Sunnah wal-Jamaa‘ah believe in and recite.
