Abū Dārim al-Tamīmī, a Kufan, a committed Shiʿite, and the leading ḥadith scholar of Kūfa.
He heard ḥadith from Ibrāhīm ibn ʿAbd Allāh al-ʿAbsi al-Qaṣṣār, Aḥmad ibn Mūsā al-Ḥammār, Mūsā ibn Hārūn, Muḥammad ibn ʿAbd Allāh Muṭayyan, Muḥammad ibn ʿUthmān ibn Abī Shayba, and several others.
Among those who narrated from him were al-Ḥākim, Abū Bakr ibn Mardawayh, Yaḥyā ibn Ibrāhīm al-Muzakkī, Abū al-Ḥasan ibn al-Ḥammāmī, the judge Abū Bakr al-Ḥayrī, and others besides.
He was credited with memorization and expertise, yet he inclined toward Shīʿism; he even composed a work vilifying certain Companions. For all that, he is not reliable in transmission. (1)
Among the elevated chains that have reached me from him is the following:
Al-Ḥasan ibn ʿAlī informed us; Jaʿfar ibn Munīr informed us; Abū Ṭāhir al-Silafī informed us; al-Qāsim ibn al-Faḍl informed us; Abū Zakariyyā al-Muzakkī informed us; Abū Bakr ibn Abī Dārim—in Kūfa—told us: Aḥmad ibn Mūsā ibn Isḥāq related to us; Abū Nuʿaym related to us, from Zakarīyā, from al-Shaʿbī, who said: I heard al-Nuʿmān ibn Bashīr say:
“The Messenger of Allah ﷺ said: ‘The lawful is clear and the unlawful is clear, and between them are doubtful matters unknown to many people. Whoever avoids the doubtful safeguards his religion and his honour, and whoever falls into the doubtful falls into the unlawful—like a shepherd who grazes around a protected pasture; he is likely to trespass upon it.’” (1)
—End of the ḥadith; it is agreed upon.
