Muslim people is Free From Responsible of Agreement With Polytheist

AT-TAWBA (REPENTANCE, DISPENSATION) : 1-4

9: 1. A (declaration) of immunity from Allah and His Messenger, to those of the Pagans with whom ye have contracted mutual alliances:-
9: 2. Go ye, then, for four months, backwards and forwards, (as ye will), throughout the land, but know ye that ye cannot frustrate Allah (by your falsehood) but that Allah will cover with shame those who reject Him.

9: 3. And an announcement from Allah and His Messenger, to the people (assembled) on the day of the Great Pilgrimage,- that Allah and His Messenger dissolve (treaty) obligations with the Pagans. If then, ye repent, it were best for you; but if ye turn away, know ye that ye cannot frustrate Allah. And proclaim a grievouenalty to those who reject Faith.
9: 4. (But the treaties are) not dissolved with those Pagans with whom ye have entered into alliance and who have not subsequently failed you in aught, nor aided any one against you. So fulfil your engagements with them to the end of their term: for Allah loveth the righteous.
