Hazrat Abdu Khair narrates that Hazrat Ali (may Allah be pleased with him) said: May Allah have mercy on Abu Bakr, he was the first person who compiled the Qur'an between two covers.

Ibn Aun narrates that the Prophet Muhammad said: When Abu Bakr was made the caliph, Ali (may Allah be pleased with him) sat among his family. Then Abu Bakr was informed of this, so he sent a messenger to call him and asked: Do you dislike my caliphate? Ali (may Allah be pleased with him) replied: No, I do not dislike your caliphate. But there was excess being done in the Qur'an, so when the Messenger of Allah (peace and blessings be upon him) passed away, I made it obligatory upon myself that I would not wear a cloak except for prayer, until I had compiled the Qur'an for the people. So Abu Bakr said: Your opinion is very good.

Imam Shabi states that Hazrat Sa’sa’ah said: The first person to compile the Quran between two covers and to make the Kalalah an heir was Hazrat Abu Bakr.
