(They will not harm you save a trifling hurt…) [3:111].
Said Muqatil: “The Jewish chieftains Ka‘b, Bahra, al-Nu‘man, Abu Rafi‘, Abu Yasir and Ibn Surya went to ‘Abd Allah ibn Salam and his followers, who had believed, and hurt them because of their acceptance of Islam and so Allah, exalted is He, revealed this verse”.
