Thumma awhayna ilayka ani ittabiAA millata ibraheema haneefan wama kana mina almushrikeen (surah Nahl: 123)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(16:123) Then We sent down this Revelation to you: "Follow the way of Abraham exclusively" and he was not one of the mushriks. *120

Summma awhainaa ilaika anit tabi` Millata Ibraaheema haneefaa; wa maa kaana minal mushrikeen

*120) This is the complete answer to the first objection (E.N. 117) raised by the disbelievers. This has two parts:
(1) There is no contradiction in the Divine Law as you seem to presume on the apparent variance in the Jewish and the Islamic Law. As a matter of fact a few things had been made unlawful especially for the Jews as punishment to them because of their disobedience; therefore, there was no reason why others should be deprived of those good things.
(2) Prophet Muhammad (Allah's peace be upon him) was commanded to follow the way of Abraham and not the way of the Jews, and they themselves knew than these things were not unlawful in the law of Abraham. For instance, the Jews did not eat the flesh of camel but this was lawful according to Abraham. Likewise, ostrich, hare, duck, etc. , were unlawful in the Jewish law, but they were lawful according to Abraham. Incidentally the disbelievers of Makkah have been warned that neither they nor the Jews had any relationship with Prophet Abraham for he was not a mushrik while both of them were practising shirk. Prophet Muhammad and his followers were the only true followers of Prophet Abraham (Allah's peace be upon them) for there was no tinge of shirk in their creed or in their practice.
