Abu Bakr his successor, was also an interesting guy.

According to Sunni Islam, Abu Bakr was instrumental in preserving the Qur'an in written form. It is said that after the hard-won victory over Musaylimah in the Battle of Yamama fought in 632, Umar (the later Caliph Umar), saw that many of the Muslims who had memorized the Qur'an ( about 300 to 700) had died in battle. Fearing that the Qur'an may be lost or corrupted, Umar requested the Caliph Abu Bakr to authorize the compilation and preservation of the scriptures in written format. After initial hesitation, Abu Bakr made a committee headed by Zayd ibn Thabit which included the memorizers of the Qur'an and Umar and to collect all verses of the book. After collecting all Qur'anic verses from texts in the possession of various sahaba, Zayd ibn Thabit and members of his committee verified the reading by comparing with those who had memorized the Qur'an. After they were satisfied that they had not missed out any verse or made any mistakes in reading or writing it down, the text was written down as one single manuscript and presented in codex form to the Caliph Abu Bakr. It is believed that this process happened within one year of the death of Muhammad when most of his sahaba (Companions) were still alive.
