Sha'ria on inequality of Muslim an non-Muslim

No Muslim can be sentenced to die for murdering a non-Muslim:

Nothing in the law of Muhammad states that the blood of the disbeliever is equal to the blood of the Muslim, because faith is necessary for equality. The people of the Covenant (Jews or Christians) do not believe in Muhammad and Islam, thus their blood and the Muslim's blood cannot be equal. These are distinctive texts which indicate that a Muslim is not to be put to death for (murdering) one of the people of the covenant or an unbeliever, but a free Muslim must be killed for a free Muslim, regardless of the race.
