He told us about 20 years ago (2005 to be precise) that Abu Ubayd al-Qaasim bn Sallaam (d.224AH), a contemporary of Al-Imaam Ahmad and others, had no hadeeth in the Kutub Sittah, I confirmed that today.
May Allaah preserve Shaykh Muhammad Awwal Amubieya on goodness.

It was in the class of Kitaab Eeman of Abu Ubayd, in a span of three or more days we finished the book under him.
Abu Ayman Al A'saliyy , Uthman Nurudeen Al Umma etc were in that class. Good old days, Maasha Allaah!
