It is narrated from Sayyiduna Zayd bin Thabit (may Allah be pleased with him) that he said: We were with the Messenger of Allah (peace and blessings be upon him) compiling (arranging) the Noble Qur'an from pieces of leather, when the Messenger of Allah (peace and blessings be upon him) said: "Glad tidings (Tuba) for al-Sham." We said: Why is that? He (peace and blessings be upon him) said: "Because the angels of the Most Merciful are spreading their wings over them (the people of al-Sham)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. And in it there is a clear statement that the compilation of the Qur'an was not completed at one time; rather, part of it was compiled in the presence of the Messenger of Allah (peace and blessings be upon him), then it was compiled in the time of Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him), and the third compilation, which is the present arrangement of the surahs, took place during the caliphate of the Commander of the Believers, Sayyiduna Uthman (may Allah be pleased with them all).
