Muhammad's Chosen People:-        
       

       Muhammad's agenda was to proclaim himself as the new Messiah, his Quran as the new Covenant, his Arabian followers as the new Chosen People, and Mecca as the new Jeusalem.

2: 143        Thus have We made of you an Ummah justly balanced that ye might be witnesses over the nations and the Apostle a witness over yourselves; and We appointed the Qiblah to which thou wast used only to test those who followed the Apostle from those who would turn on their heels (from the faith).  Indeed it was (a change) momentous except to those guided by Allah.  And never would Allah make your faith of no effect.  For Allah is to all people most surely full of kindness Most Merciful.

5: 3        Forbidden to you (for food) are: dead meat blood the flesh of swine and that on which hath been invoked the name of other than Allah that which hath been killed by strangling or by a violent blow or by a headlong fall or by being gored to death; that which hath been (partly) eaten by a wild animal; unless ye are able to slaughter it (in due form); that which is sacrificed on stone (altars); (forbidden) also is the division (of meat) by raffling with arrows: that is impiety.  This day have those who reject faith given up all hope of your religion: yet fear them not but fear Me.  This day have I perfected your religion for you completed my favor upon you and have chosen for you Islam as your religion.  But if any forced by hunger with no inclination to transgression Allah is indeed Oft-Forgiving Most Merciful.

22: 78 And strive in His cause as ye ought to strive (with sincerity and under discipline): He has chosen you and has imposed no difficulties on you in religion [deen]; it is the cult [millata] of your father Abraham.  It is He Who has named you Muslims both before and in this (Revelation); that the Apostle may be a witness for you and ye be witnesses for mankind! So establish regular Prayer give regular Charity and hold fast to Allah! He is your Protector the Best to protect and the Best to help!        
       
24: 55 Allah has promised to those among you who believe and work righteous deeds that He will of a surety grant them in the land inheritance (of power) as He granted it to those before them; that He will establish in authority their religion the one which He has chosen for them; and that He will change (their state) after the fear in which they (lived) to one of security and peace: `They will worship Me (alone) and not associate aught with Me.'  If any do reject faith after this they are rebellious and wicked.

Sahih Al-Bukhari HadithHadith 4.693        Narrated byAbu Huraira
The Prophet said, "We are the last (to come) but we will be the foremost on the Day of Resurrection, nations were given the Book (i.e. Scripture) before us, and we were given the Holy Book after them. This (i.e. Friday) is the day about which they differed. So the next day (i.e. Saturday) was prescribed for the Jews and the day after it (i.e. Sunday) for the Christians. It is incumbent on every Muslim to wash his head and body on a Day (i.e. Friday) (at least) in every seven days."
