Who Is Creater ?

That is Allah, your Lord, there is no god but He; the Creator of all things, therefore serve Him, and He has charge of all things. 

(Soreh Al-Anaam{Verse No.102}

Amazing Eart And Heaven

Wonderful Originator of the heavens and the earth! How could He have a son when He has no consort, and He (Himself) created everything, and He is the Knower of all things.
(Surah Al-Anam) {Verse No.101}

If Prophet give you anything !!

Whatever Allah has restored to His Messenger from the people
of the towns, it is for Allah and for the Messenger, and for
the near of kin and the orphans and the needy and the wayfarer,
so that it may not be a thing taken by turns among the rich of you,
and whatever the Messenger gives you, accept it, and from whatever
he forbids you, keep back, and be careful of (your duty to) Allah;
surely Allah is severe in retributing (evil)
(Soreh Hashir) {Verse 7}

How Says Prophet Muhammad S.A.W

Nor does he speak out of desire. {3}
It is naught but revelation that is revealed, {4}

(Surah Najam)

If you not obey prophet then you would not obey allah

Whoever obeys the Messenger, he indeed obeys Allah,
and whoever turns back, so We have not sent you as a
keeper over them..
(Soreh Nisa) {Verse No.80}

Why Muslims follow Prophet Muhammad S.A.W

But no! by your Lord! they do not believe (in reality)
until they make you a judge of that which has become a
matter of disagreement among them, and then do not find
any straitness in their hearts as to what you have decided
and submit with entire submission..
(Soreh Nisa){Verse No.65}

A true Muslim must consider it

O you who believe! obey Allah and obey the Messenger
and those in authority from among you; then if you
quarrel about anything, refer it to Allah and the Messenger,
if you believe in Allah and the last day; this is better and
very good in the end. 
(Soreh Nisa) {Verse No.59}
