Islam is a religion sent by the Lord of the worlds to all worlds, to all the children of Adam till the Resurrection day, to all human races.  What lay credence to this fact is : the Holy Quran , the prophet's Hadiths and rule system that the prophet followed, his Caliphs and those who followed them over the span of history. We will cast some light on each of this evidence in separate articles. Most of the Quran chapters start with "O' people" We will start with the Holy Quran; God says in the Holy Quran what means:

1-    Praise be to God, the lord of the worlds(1:1)

2-     Blessed is He who sent down the criterion to His servant, that it may be an admonition to all creatures;- (25:1)

3-     We have not sent thee but as a universal (Messenger) to men, giving them glad tidings, and warning them (against sin), but most men understand not. (28) (34:28)

4-    Say: "O men! I am sent unto you all, as the Messenger of Allah, to Whom belongeth the dominion of the heavens and the earth:( 7:158)

5-     If anyone desires a religion other than Islam (submission to Allah), never will it be accepted of him; and in the Hereafter He will be in the ranks of those who have lost (All spiritual good). (3:85)

6-    "This is no less than a Message to (all) the Worlds. (87) "And ye shall certainly know the truth of it (all) after a while." (38:87-88)

7-    This Qur'an hath been revealed to me by inspiration, that I may warn you and all whom it reaches. (6:19)

8-    It is He Who has sent His Messenger with Guidance and the Religion of Truth, that he may proclaim it over all religion, even though the Pagans may detest (it). (61: 9)

9-    We sent thee not, but as a Mercy for all creatures. ( 21:107)

These verses are quite enough, they are clear-cut evidence that Islam is universal religion, for every nation, every time and every race. When you open the first page you will find the first verse reads

" Praise be to Allah, the Lord of the worlds."
