76. When the Jewish rabbis found no grounds for criticizing the fundamental teachings of the Prophet (there was no difference between the teachings of the previous Prophets and that of the Arabian Prophet on matters which constitute the core of religion), they raised objections about the details of religious law. The first objection was that the Prophet (peace be on him) had declared lawful a number of things which had been reckoned as unlawful since the time of the ancient Prophets. What is said here is a refutation of that objection.
77. If 'Israel' is taken to mean the 'Children of Israel' then the interpretation of this verse must be that before the revelation of the Torah they treated a number of things as prohibited on the grounds of custom and usage alone. If, however, 'Israel' signifies Jacob (Ya'qub) then, the meaning is that he avoided the use of certain foods, which his descendants wrongly understood to be religiously prohibited, as a result of either a temperamental dislike or an ailment. This latter version is more commonly accepted. It becomes clear from the next verse that the Biblical injunction regarding the prohibition of the flesh of camels and rabbits was not part of the original Torah but an interpolation by Jewish doctors.
