What Quran Says About Muhammad?
Prophet Muhammad(Peace be upon to Him)
[21:107] We have not sent you (Prophet Muhammad) except as a mercy to all the worlds.

MUHAMMAD is not the father of any of your men, but (he is) the Messenger of Allah, and the Seal of the Prophets: and Allah has full knowledge of all things. [33:40]

MUHAMMAD is the apostle of Allah. and those who are with him are strong against Unbelievers, (but) compassionate amongst each other. Thou wilt see them bow and prostrate themselves (in prayer), seeking Grace from Allah and (His) Good Pleasure. On their faces are their marks, (being) the traces of their prostration. This is their similitude in the Taurat; and their similitude in the Gospel is: like a seed which sends forth its blade, then makes it strong; it then becomes thick, and it stands on its own stem, (filling) the sowers with wonder and delight. As a result, it fills the Unbelievers with rage at them. Allah has promised those among them who believe and do righteous deeds forgiveness, and a great Reward. [48:29]

MUHAMMAD is no more than an apostle: many Were the apostle that passed away before him. If he died or were slain, will ye then Turn back on your heels? If any did turn back on his heels, not the least harm will he do to Allah. but Allah (on the other hand) will swiftly reward those who (serve Him) with gratitude. [3:144]

But those who believe and work deeds of righteousness, and believe in the (Revelation) sent down to MUHAMMAD - for it is the Truth from their Lord,- He will remove from them their ills and improve their condition. [47:2]
