88 Verse 83 referred to the universal moral law. This verse 84 refers to its application under a special Covenant entered into with the Jews of Mad i nah by the newborn Muslim Commonwealth under its Guide and teacher Muhammad. This Covenant is given in Ibn Hisham's Sirat al Rasul, and comments on it will be found in Ameer 'Ali 's Spirit of Islam ( London , 1922), pp. 57-61. It was entered into in the second year of the Hijrah, and was treacherously broken by the Jews almost immediately afterwards.
