Surely the (true) religion with Allah is Islam, and those to whom the Book had been given did not show opposition but after knowledge had come to them, out of envy among themselves; and whoever disbelieves in the communications of Allah then surely Allah is quick in reckoning.

And it does not behoove a believer to kill a believer except by mistake, and whoever kills a believer by mistake, he should free a believing slave, and blood-money should be paid to his people unless they remit it as alms; but if he be from a tribe hostile to you and he is a believer, the freeing of a believing slave (suffices), and if he is from a tribe between whom and you there is a convenant, the blood-money should be paid to his people along with the freeing of a believing slave; but he who cannot find (a slave) should fast for two months successively: a penance from Allah, and Allah is Knowing, Wise.

Say: I am forbidden to serve those whom you call upon besides Allah when clear arguments have come to me from my Lord, and I am commanded that I should submit to the Lord of the worlds.
