refuting this suspicion 

the prayer upon the prophet from the almighty allah and from us doesn’t suggest the prophet’s need, but it is to show allah’s honour, pride and respect to him and that of us too.

it is not, as some insulters say, that the prophet gets more advantages because allah forgave him from any done sin.

any fair comparison between prophet muhammad and all sent prophets before shows the prophet’s degree that reaches completeness. that is because the world doesn’t need any other messages or messenger after islam and muhammad (pbuh).

the prophet’s message is the last and only complete one among all other earlier messages. it covers all human needs, laws, organisations and treatments and how to apply morals and built great cultures.

such important things were not found in any other religion except islam.

and as for muhammad’s message, it is the mercy sent for all mankind:

” and we have sent you (o muhammad) not but as a mercy for the 'alamin (mankind, jinns and all that exists). “ (al anbia’:107)

the message of islam is not sent to a special folk as it was the case of many earlier folks like :

the folk of aad,

 “and to 'ad (people, we sent) their brother hud. he said: "o my people! worship allah! you have no other ilah (god) but him." (al a’raf:65)
 

the folk of thamud,

“and to thamud (people, we sent) their brother salih (saleh). he said: "o my people! worship allah! you have no other ilah (god) but him” ( al a’raf : 73)

or the folk of madyan.

“and to (the people of) madyan (midian), (we sent) their brother shu'aib. he said: "o my people! worship allah! you have no other ilah (god) but him.”

and so was the case with any other prophet, except muhammad’s message that is sent to the whole world:

“and we have sent you (o muhammad) not but as a mercy for the 'alamin (mankind, jinns and all that exists)." (al anbia’:107)

“and we have not sent you (o muhammad) except as a giver of glad tidings and a warner to all mankind, but most of men know not.” (saba’:28)

and as mentioned before, islam is the last and lasting message that organizes all people’s life and offers them all their needs everywhere anytime for their best in this life and the hereafter:

“muhammad is not the father of any man among you, but he is the messenger of allah and the last (end) of the prophets. and allah is ever all-aware of everything.“ ( al ahzab:40)

and the almighty allah said, describing islam as being the message that came to complete all other messages:

“this day, i have perfected your religion for you, completed my favour upon you, and have chosen for you islam as your religion.“( al ma’idah : 3)

this message is the only complete one and is the last one that will continue on this earth till the end of this life.

“  it is he who has sent his messenger (muhammad ) with guidance and the religion of truth (islam), to make it superior over all religions even though the mushrikun (polytheists, pagans, idolaters, disbelievers in the oneness of allah) hate (it).“  (at tauba:33)

“he it is who has sent his messenger (muhammad ) with guidance and the religion of truth (islam), that he may make it (islam) superior over all religions. and all-sufficient is allah as a witness. “

(al fateh: 28)

“he it is who has sent his messenger (muhammad ) with guidance and the religion of truth (islamic monotheism) to make it victorious over all (other) religions even though the mushrikun (polytheists, pagans, idolaters, and disbelievers in the oneness of allah and in his messenger muhammad ) hate (it).“ (as saf: 9)
