"Nay, but we hurl the true against the false, and it hoth break its head and lo! it vanisheth. And yours will be woe for that which ye ascribe (unto him)." - Holy Quran 21:18.
The Submitters, claim from the Quran that the messenger mentioned in the Holy Quran, 3:81, was their leader Rashid Khalifa and Muhammad . They have put several articles on the web to prove their claim. They have a well defined articles and literature of their own, and is widely circulated among muslims and non-muslims.
The General Muslims, have no objections, if somebody wants to show some miracles from the Quran. But if somebody distorts the meaning of the Quran, or tries to propagate false teachings through that, then we object.
"There is among them a section who distort the Book with their tongues: (as they read) you would think it is a part of the Book, but it is no part of the Book; and they say, "That is from Allah. But it is not from Allah: It is they who tell a lie against Allah, and well) they know it!" Holy Quran 3/78
The Submitters, claim that their Leader, Rashid Khalifa, was a messenger of Allah, and they have written articles to support it. Here we will try to look at those articles and find out how true their claim is. Since the Submitters believe only in Quran and no hadith, we will examine everything in the proof of Quran only. And we hope that a sincere reader will appreciate our article.
"There are those who purchase error at the price of guidance, so their commerece doth not prosper, neither are they guided. Their likeness is as the likeness of one who kindelth fire, and when it sheddeth light around him Allah taketh away their light and leaveth them in darkness, where they cannot see, Deaf, dumb and Blind; and they returneth not." - Holy Quran 2:16-18
Rashid Khalifa, Messenger or Not.
"(O man), follow not that whereof thou hast no knowledge. Lo! the hearing and the sight and heart - of each of these (who follow) it will be asked (on the Day of Reckoning)". Holy Quran 17/36
The Claim of submitters, that Rashid Khalifa was a messnger, stems from the Holy Quran 3:81
Behold! Allah took the Covenant of the Prophets, saying: "I give you a Book and Wisdom; then comes to you A Messenger, confirming what is with you; do you believe him and render him help." Allah said: "Do ye agree, and take this my Covenant as binding on you?" They said: "We agree." He said: "Then bear witness, and I am with you among the witnesses." - Holy Quran 3:81 
They claim that in the above verse Prophet Muhammad is also included, to be a part of all prophets. But this is not possible. My reasons for objections are:
1. This complete set of verses above and below 3:81 is the rebuttal for the claim of the people of book, that Muhammad is not a prophet.
2. To show that, the above point is valid, read the verses below that till 3:84, where allah states:
Say: "We believe in Allah, and in what has been revealed to us and what was revealed to Abraham, Isma'il, Isaac, Jacob, and the Tribes, and in (the Books) given to Moses, Jesus, and the Prophets, from their Lord: we make no distinction between one and another among them, and to Allah do we bow our will (in Islam)." - Holy Quran 3:84 
If the messenger in verse 3:81 would have been Rashid Khalifa, then 3:84 would have included the name of Muhammad .
3. The Word Prophet and Messenger has been used interchangably, in the Translation of the Quran. There actually is no distinction between a Messenger and Prophet. All Prophets when they come they bring along with them the Message of Allah, and hence they are the messengers of Allah.
4. If we read 33:40 Allah says:
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. - Holy Quran 33:40 
So, this verse clearly says that there Muhammad is the Last of the Prophet or Messengers, and there is not going to be any messenger after him.
So now having been baseless, they try to show that the covenant in 3:81 is applicable to Prophet Muhammad also. For this they give reference to Holy Quran 33:7.
So lets see what Allah says in 33:7 :
And remember We took from the Prophets their Covenant: as (We did) from thee: from Noah, Abraham, Moses, and Jesus the son of Mary: We took from them a solemn Covenant: - Holy Quran 33:7 
But what was this covenant mentioned in 33:7. For this we have to read the verse after that.
That (Allah) may question the (Custodians) of Truth concerning the Truth they (were charged with): and He has prepared for the Unbelievers a grievous Penalty. - Holy Quran 33:8 
This clearly proves that the Covenant in Surah 33 is regarding the message of Allah. What Allah has given to his Prophets, regarding the belief in Allah, and there being no other Gods than Allah. This is Not at all related with the Covenant of Surah 3, mentioned above. Both of them together are out of context. The Context of these starting verses in the above surah, is regarding the believers: that they will be tried, as those that were before them. This could be seen clearly from 33:9 and the verses after that, where Allah clearly says, that the believers before were tried, so will be the believers at that time. But Allah, promises That he will reward the believers and punish the Hypocrites (33:24).
The Theory of the Last Prophet
To support their theory, that Prophets wont come on earth now, since Muhammad was the last prophet, but messengers can they take help of another verse. Lets see that verse, 40:34 :
"And to you there came Joseph in times gone by, with Clear Signs, but ye ceased not to doubt of the (mission) for which he had come: at length, when he died, ye said: `No Messenger will Allah send after him.' Thus doth Allah leave to stray such as transgress and live in doubt" - Holy Quran 40:34 
In the Above verse Allah clearly says, that those PEOPLE WHO HAD DOUBT OF THE MESSAGE OF ALLAH THOUGHT THAT NO MORE PROPHETS WILL COME. But Allah never said so. The Submitters have clearly mis-interpreted this verse, and say that Allah said, Joseph was the Last Prophet but he send Prophets after that. Allah answers such people in the verse next to that:
"(Such) as dispute about the Signs of Allah, without any authority that hath reached them. Grievous and odious (in such conduct) in the sight of Allah and of the Believers. Thus doth Allah seal up every heart of arrogant and obstinate transgressors."
Are Muslim Idolators
The Submitters claim that all Muslms are Idolators, since they join the name of Prophet Muhammad along with Allah in the Sahadah. But is this claim really true. The Muslim when he takes up his Sahadah clearly says, "There is no God except Allah and Muhammad is the Prophet of Allah". Clearly this is not the Joining of Prophet as a God, but they are misinterpreting it.
The Prophet Muhammad was to be given due respect by all of the people of the world. In Quran Allah says in 2:104, that the prophet has to be given more respect than ordinary men. The natrul question is why only Prophet Muhammad , why not all other prophets which had come before. They also brought the same religion, they were also muslims. Here we have to remember, that all the Messengers which came before, came to particular region. Their message was Time bound and Space Bound. Muhammad was the universal messenger (Quran 34:28).
In the Adhan the Muezzin calls, "Ashado Anna Muhammadur Rasolullah", which means, "I bear witness that Muuhammed is the Prophet of Allah". Clearly there is no sign of joining him as a partner of Allah. This was the same Adhan which was given when the Prophet was Alive, and has been recorded in All the historical books. All Muslims, follow the same Adhan till day.
One of their claims also state, that Muslims have accepted Prophet Muhammad sinless, from birth till death, which is not true. Let us see, that is the prophet really a nice man. Is he good enough to be followed by Muslims.
Ye have indeed in the Messenger of Allah a beautiful pattern (of conduct) for any one whose hope is in Allah and the Final Day, and who engages much in the praise of Allah. - Quran 33:21 
Allah clearly tells here, about the prophet's qualities.
Do we need messengers
The idea, which clicked Rashid Khalifa, about being messenger, since no Prophets are going to come stems probably from Bible. When God stopped sending Prophets to Israel, there were Judges, who warned the people to cokme to the right path and not to be led astray by Satan.
Allah says, in the Holy Quran, 5:3, That he has perfected our Religion, the religion of Islam. After the Prophet Muhammad, no one was to come and do modification in it.
Since Islam is already been perfected, we do not need any mesengers, to come and warn us or show us some miracles, and claim that he is a messenger or a prophet.
We have the Book (Quran) with us, we need to analyze that and that only and find out what is true.
Can Devil change verses in Quran ?
The Submitters claim that after the Quran was written, the Devil caused misceif and added two verses in the Quran, which was not there. They have removed these two verses from their Quran. But here we have to look at the message of Allah:
Nay, this is a Glorious Qur-an, (Inscribed) in a Tablet Preserved! - Holy Quran 85:21-22
Those who reject the Message when it comes to them (are not hidden from Us). And indeed it is a Book of exalted power. No falsehood can approach it from before or behind it: it is sent down by One Full of Wisdom, Worthy of all Praise. - Holy Quran 41:41-42 
These verse clearly tells us, that the Quran is Preserved by Allah, and no Falsehood will ever approach it. So this idea of two verses being wrong in it, is not valid. Allah says:
"... Do you believe in part of the Book and disbelieve in another part? And what is the reward of those who do so save ignominy in the life of the world, and on the Day of Resurrection they will be consigned to the most grievous doom ..." Holy Quran 2:85 
So, this book quran has to be believed in whole. Removing two verses also removes you from the claim of believer.
