Musannaf Ibn Abi Shaybah 32035 — What a man does when he completes

Al-Hakam said: Mujahid, Abdah bin Abi Lubabah and some people used to collate the copies of the Qur'an with one another. On the day they intended to complete it, they sent a messenger to me and to Salamah bin Kuhayl to call us, and they said: "We have been collating the copies of the Qur'an, and today we intend to complete it. We would like you to be present with us, for it used to be said: 'When the Qur'an is completed, mercy descends at the time of its completion,'" or he said: "'mercy is present at the time of its completion.'"
