bayhaqi:7313ʿUbaydullāh b. ʿUmar > al-Qāsim b. Muḥammad > Yaṣdaʿuhā

[Machine] He said, "It is divided into three types of headaches: one-third is the best, one-third is average, and one-third is the worst." The believer should choose the best option and take from the average. Abu Bakr Al-Asbahani informed us that Abu Nasr Al-Iraqi narrated from Sufyan Al-Jawhari, who narrated from Ali Ibn Al-Hasan, who narrated from Abdullah Ibn Al-Walid, who narrated from Sufyan Al-Thawri, that both of them narrated from them all. Al-Shafi'i mentioned these two schools without naming their proponents, and we have also narrated from Al-Zuhri a statement similar to that of Al-Qasim and we have narrated from Umar Ibn Al-Khattab that he said, "The owner of the flock should choose one-third, and then choose from the remaining two-thirds."
