Assessing the theory of Ibn Tamimiye regarding denying Ibn-e Abbas as the student of Imam Ali (a.s) and critiquing the theory according to Sunni resources

Imam Ali's (a.s) religious authority became one of the issues in Islamic society after demise of the Prophet of Islam (s.a). This issue has been so outstanding that many of Mohadethan, commentators, jurists and historians wrote about it. Imam Ali (a.s) was so prominent that many of the great companions of the Prophet were proud of being student of him, namely Ibn-e Abbas, who was given various titles as ''Habr Al-Aemeh, Bahr, Tarjoman Al-Quran, Rais Al-Mofaserin and Faqih Al-Asr'. He was one of students of Imam Ali (a.s) and considered this fact as an honor. Ibn-e Tamimiye denies the fact that Ibn-e Abbas was Imam Ali's student; whereas, according to Sunni resources, Ibn-e Abbas has stipulated that the origin of his knowledge in exegesis of the Quran was Imam Ali (a.s). Ibn-e Abbas has introduced Imam Ali (a.s) as his best teacher after the Prophet (s.a). Confronting Ahl-e Bayt (a.s) and intending to weaken the position of Imam Ali's religious authority and promoting such authority for others, Ibn-e Tamimiye constantly attempted to ignore or justify several of the indisputable historical realities. His viewpoints regarding denial of Ibn-e Abbas's studentship with Imam Ali (a.s) is not acceptable due to the historical facts and the issue requires assessment.
