For the first Generation Tanna sage with a similar name, see Abba Saul ben Batnit. Tomb of Abba Saul and his wife Abba Saul (, Abba Shaul) was a fourth generation Tanna (Jewish sage). His elder contemporary was Akiva ben Joseph. Many Masoretes in the Talmud cite him engaging in the topics of the Temple in Jerusalem and the holy work done there.

He was tall at sight, and the Talmud (Babylonian, Tractate "Niddah" 61a) depicts R. Tarfon reaching only up to R. Saul's shoulder. Saul was a grave-digger. (Babylonian, Tractate Niddah 24b)

In the Talmud, Tractate "Yebamoth" (Levirate marriage), Abba Saul was stringent, and demanded that a levir (a "Yabbam", the brother of the deceased) should have pure-sacred intentions:

Abba Saul opined that in his days there was nowhere to be found a levir with a mitzvah (commandment) intention, and thus he revokes the commandment of the yibbum, replacing it with the Halizah.
