In our quest to study traditions regarding ʿAlī b. Abī Ṭālib's collection of the Qur’an, I have, in total, examined 27 traditions. Out of these 27 traditions, seven variants were attributed to Abū Jaʿfar, six to ʿAlī b. Abī Ṭālib himself, four to Jaʿfar al-Ṣādiq and ten variants were attributed to Ibn Sīrīn. Some of the traditions were recorded in the earliest Shiʿi sources, namely al-Ṣaffār's Baṣāʾir al-Darajāt, al-Kulaynī's al-Kāfī, ʿAlī b. Ibrāhīm al-Qummī's Tafsīr al-Qummī and Ibn al-Nadīm's Kitāb al-Fihrist, which were written in the third and fourth centuries. The remaining traditions were recorded in Sunni sources written between the third and sixth centuries. These include ʿAbd al-Razzāq's Muṣannaf, Ibn Abī Shayba's Muṣannaf, Muḥammad b. Saʿd's al-Ṭabaqāt al-Kabīr, Ibn Abī Dāwūd's Kitāb al-Maṣāḥif, Aḥmad b. Fāris's al-Ṣāḥibī fī al-Fiqh, al-Ḥaskānī's Shawāhid al-Tanzīl, al-Khwārizmī's al-Manāqib, Abū Nuʿaym's Ḥilyat al-Awliyā, Ibn Shahrāshūb's Manāqib Āl Abī Ṭālib, Ibn al-Ḍurays al-Bajalī's Faḍā’il al-Qurʾān, and Ibn ʿAbd al-Barr's al-Istīʿāb fī Maʿrifat al-Aṣḥāb.

In addition to the 27 traditions, I have located four more traditions on the issue but could not fit them into any of the groups. Therefore, I decided to not to examine them, apart from the tradition that was recorded in Sulaym b. Qays al-Hilālī's Kitāb. Since the book was thought to be written in a very early period (first or second centuries AH) I thought it important to analyse the tradition recorded in it. Thus, in total we end up with 31 traditions regarding ʿAlī b. Abī Ṭālib's collection of the Qur’an. This number is close to the number of variants that Motzki treated in his study of Sunni traditions on the collection of the Qur’an. He gathered 29 traditions about Abū Bakr's collection of the Qur’an and 22 traditions about ʿUthmān's collection of the Qur’an, which all intersected at al-Zuhrī (d. 124/742).

In the examination of the traditions S1, S2 and K1, which were attributed to Abū Jaʿfar, I found that we could initially trace the variants back to Ibn Abī al-Khaṭṭāb's sources Muḥammad b. Sinān (d.220) and al-Naḍr b. Shuʿayb (d.210).
