Abu Zar'a al-Razi: Thiqah (trustworthy)
Ahmad ibn Hanbal: Thiqah (trustworthy), how sound is his hadith
Ahmad ibn Shu'ayb al-Nasa'i: Not strong (in hadith transmission)
Ibn Hajar al-'Asqalani: Saduq (truthful), once: Agreed upon his trustworthiness but al-Nasa'i was strict with him
al-Dhahabi: Saduq (truthful), and once: Thiqah (trustworthy) and an authority
Authors of Tahrir Taqrib al-Tahdhib: Saduq (truthful), and the saying of al-Dhahabi: 'Thiqah (trustworthy) and an authority', needs further consideration, rather so does everyone who declared him trustworthy without qualification, for Yahya al-Qattan and al-Nasa'i must have known something others didn't, and Allah knows best
Yahya ibn Ma'in: Thiqah (trustworthy)
