A sabab put forward by both al-Wāhidī (Kitāb 22) and al-Suyūtī (Lubāb 19) claim this verse was revealed about those Jews of Medina who urged their converted relations to obey Muhammed's example even while they hypocritically refused to do so themselves (such Jewish hypocrisy being a common Qur'ānic polemical motif). The sabab thus fixes the meaning of the pronoun "ye", and also provides a gloss for the word "right conduct" (birr) as the Sunnah of Muhammed.
