History does not lie, that is why some people remain ignorant to it, but Mohammed stole his customs off Jews and when they did not accept his beliefs he made a proclamation to kill them.
As for Christians that believe on this Sunday Worship Deception. The history speaks for it self that is why he said REMEMBER the Sabbath day because he knew you would forget it.
Exo 20:8 Remember the sabbath day, to keep it holy.
Exo 20:9 Six days shalt thou labour, and do all thy work:
1Ki 8:56 Blessed be the LORD, that hath given rest unto his people Israel, according to all that he promised: there hath not failed one word of all his good promise, which he promised by the hand of Moses his servant.
