伊玛目苏夫彦·赛怀里（Sufyaan ath-Thawree）生于公元719年的库法。他深入研习圣训与教法之后，成为库法圣训学派的主要教法学者。他的观点与同时代的艾卜·哈尼法（Abu Haneefah）相近，但他反对后者运用类比推理（Qiyaas）和善断（Istihsaan）。

Imaam Sufyaan ath-Thawree was born in Kufah in the year 719 CE, and after an extensive study of Hadeeth and Fiqh became the main Fiqh scholar of the Hadeeth school in Kufah. He held similar views to those of his contemporary, Abu Haneefah, however he opposed the latter’s use of Qiyaas and Istihsaan.

由于伊玛目苏夫يان（Sufyaan）直言不讳，并拒绝支持与伊斯兰教法相抵触的国家政策，他与阿拔斯政权的官员之间发生了一系列冲突。哈里发曼苏尔（Caliph al-Mansoor，在位时间为公元759年至744年）曾致信伊玛目萨乌里（ath-Thawree），请他出任库法的卡迪（Qaadee），条件是他不得作出任何与国家政策相悖的判决或裁决。苏夫يان收到信后，满怀厌恶地将信撕碎，扔进了底格里斯河。然而，由此他被迫停止授课，逃亡避难。他一直隐匿至公元777年去世。

There occurred between Imaam Sufyaan and officials of the ‘Abbaasid state a series of confrontations due to his outspoken nature and his refusal to support state policies which contradicted the Sharee’ah. Caliph al-Mansoor (rule 759-744 CE) Sent a letter to Imaam ath-Thawree requesting him to accept the post of Qaadee of Kufah on condition that he not make any judgement or ruling in opposition to the state policy. On receipt of the letter, Sufyaan tore it up and threw it into the Tigris river in disgust, but, as a result, he was forced to give up his teaching and flee for his life. He remained in hiding until he died in the year 777 CE.

以下是两个主要因素:

The two main factors are as follows:

伊玛目一生的大部分时间都在隐匿中度过，因此无法吸引大量学生，使他的观点在学术圈中得以传播。

(a) The Imaam spent the greater part of his life in hiding and thus was unable to attract a large number of students who might subsequently spread his opinions in the circles of learning.

(b) 尽管他确实进行了相当广泛的圣训及其释义的汇编，但他在遗嘱中要求其主要学生‘Ammaar ibn Sayf 销毁他所有的著作，无法擦除的则予以焚毁。‘Ammaar 遵从老师的嘱托，销毁了其著作，但Imaam的许多观点已被其他Imaam的学生记录下来，因此得以流传至今，只是并未形成系统的体系。142

(b) Although he did carry out some fairly extensive compilation of Hadeeths and their interpretations, he requested in his will that his main student, ‘Ammaar ibn Sayf, erase all his writings and burn whatever could not be erased. ‘Ammaar dutifully destroyed his teacher’s writings, but many of the Imaam’s ideas were recorded by students of other Imaas, so they have survived till today but not in an organized form.142
