Abu al-Fath ibn Abi al-Fawaris: His books were of poor quality.

Abu Bakr al-Barqani: I have always heard people say that Umar was one of those who were successful in selection, and people used to write a lot based on his selection. Umar had selected (hadiths) from Ali ibn al-Swaff - I think he said about twenty parts.

al-Hasan ibn Ahmad al-Sabi'i: A liar, a liar.

al-Khatib al-Baghdadi: People used to write based on his transmission and listen to his selection over the sheikhs. Al-Daraqutni erred in many of his criticisms of Umar.

al-Daraqutni: He traced Umar's errors in what he selected, especially from Abu Bakr al-Shafi'i, and wrote a treatise on it. Al-Baghdadi found that all the errors that Abu al-Hasan mentioned applied to Umar, except for two places.

al-Dhahabi: Truthful, but he has errors and misconceptions.

Abd al-Hayy ibn al-'Imad al-Hanbali: The hafiz (scholar of hadith) and innovator, but he was not precise.
