101 – al-Qaddāḥ, Abū ʿUthmān Saʿīd ibn Sālim al-Makkī * (D, S)
An imam and ḥadith scholar, Abū ʿUthmān Saʿīd ibn Sālim al-Makkī, known as al-Qaddāḥ.
He transmitted from: Ibn Jurayj, ʿUbayd Allah ibn ʿUmar, Yūnus ibn Abī Isḥāq, Sufyān al-Thawrī, and a number of others.
Those who narrated from him include: Sufyān ibn ʿUyaynah and Baqiyyah ibn al-Walīd—both senior to him—as well as Imām al-Shāfiʿī, Asad ibn Mūsā, Abū ʿAmmār al-Ḥusayn ibn Ḥurayth, ʿAlī ibn Ḥarb, and others.
Yahya ibn Maʿīn said, “There is nothing wrong with him.” (1)
ʿUthmān ibn Saʿīd al-Dārimī said, “He is not all that.”
Muḥammad ibn Abī ʿAbd al-Raḥmān al-Muqriʾ said, “I wrote down his narrations, and he was a Murjiʾ.”
= On the authority of an unnamed transmitter, from Ata ibn Abi Rabah, from Zayd ibn Arqam, who reported that the Messenger of Allah ﷺ said: “Whoever performs the pilgrimage on behalf of his father or his mother, it suffices for him and for both of them.” Al-Haythami comments in al-Majmaʿ 2/283: “Its chain contains an unidentified narrator.”
