1 - As for the ḥadīth of Ibn Masʿūd, it is narrated by Muḥammad ibn Sābiq from Isrāʾīl, from Abū Sinān, from Abū al-Aḥwaṣ, from him, in a marfūʿ form, with the addition of "the Great" in place of the ellipsis, and an explanation of it will follow. It was recorded by al-Ḥākim (1/511) who said: "Authentic according to the criteria of al-Bukhārī and Muslim." Al-Mundhirī affirmed this in "al-Targhīb" (2/269), and then al-Dhahabī in "al-Talkhīṣ," but he said: "I say: Abū Sinān is Ḍirār ibn Murrah, whom al-Bukhārī did not include." This means it is exclusive to Muslim, and it is as he said, and he is trustworthy like the rest of its narrators, who are mentioned in "al-Tahdhīb" except for the teacher of al-Ḥākim: Bakr ibn Muḥammad al-Ṣayrafī, who is al-Marwazī al-Dukhmasīnī, which is his nickname, and he was a virtuous scholar, with a good biography in "Ansāb al-Samʿānī," and al-Ḥāfiẓ al-Dhahabī described him in "Tadhkirat al-Ḥuffāẓ" as a ḥadīth scholar of Marw, mentioning his death in the year 345. His teacher in this ḥadīth was mentioned by al-Khaṭīb in "Tārīkh Baghdād" (4/250-251) with the narration of a group of trustworthy ḥadīth scholars from him, and he said: "He was trustworthy and reliable, and he died in the year 279." Then I saw that al-Ḥākim had recorded it in another place (2/117-118) through the route of Muḥammad ibn Yūsuf al-Firyābī: Isrāʾīl narrated to us without the word "the Great," and he said: "Authentic according to the criteria of Muslim." Al-Dhahabī agreed with him. Al-Nawawī affirmed this in "al-Riyāḍ" (664/1882)
