Ibraheem ibn Ishaaq al Harbee stated: "I have met three people whom you will never find the likes of them, women would be unable to give birth to the likes of them. I met Abu 'Ubayd al Qaasim ibn Salaam, nothing is like him except a mountain that a soul has been blown into…"
Hilaal ar Raqee stated: "Allaah has blessed the Muslims with these four; Ash Shaafi'ee in his understanding of Fiqh and Hadeeth, Ahmad ibn Hanbal in the Mihnah, Yahyaa ibn Ma'een in negating the lies and Abu 'Ubayd in explaining the difficult words in Hadeeth.
