Among the issues which is debated between Shi’i exegetes and some of Sunni exegetes are the references of the verse “Allah, and whosoever hath knowledge of the Scripture, is sufficient witness between me and you”. Shi’i exegetes and some of Sunni exegetes are of the opinion that the reference of this verse is Imam Ali (A.S). On the other hand, some Sunni exegetes think that ‘Abdullah Ibn Salam, Jew and Christian scholars, and “all believers” are three more references of this verse.Studying various views if the Sunni and Shi’i exegetes and analyzing these views, this article has criticized applying the verse to references other than Imam Ali (A.S) and emphasized the claim made by Shi’i exegetes. Hadiths quoted from the Household (A.S), Companions, and Followers who have regarded Imam Ali (A.S) as the only reference of this verse, extent of the Imam’s knowledge, disagreement between applying the verse to other verses on the one hand and historical documents on the other are among objections posed against the view adopted by Sunni exegetes.
