Personality of Muhammad the Messenger of God (peace be upon him).
1. He was of an exemplary character.
Indeed in the (Prophetic) Messenger of Allah you have an excellent example (to follow) for him whose hope is in Allah and the Last Day and remembers Allah much. (33:21)
And most surely, you have an exalted moral character. (68:4)
2. He was truthful in conveying the message.
And when the Muslim believers saw the confederate forces (of non-believers), they said: “This is what Allah and His (Prophetic) Messenger promised us, and Allah and His (Prophetic) Messenger told (us) the truth”, and it only added to their Faith and submission (to Allah). (33:22)
3. God vouches for his arbitration and judgment.
But, nay, by your Lord, they do not have (real) Faith until they make you judge of what is in dispute between them and find within themselves no dislike of that which you decide, but submit with full submission. (4:65)
The response of the believers when summoned to Allah and His (Prophetic) Messenger that he may judge between them is only that they say: “We hear and we obey”. And it is such as these who are the successful. (24:51)
4. He was of honoured and noble disposition.
It (the Qur’an) is indeed the Word (of Allah, brought) by an honoured (Prophetic) Messenger. (69:40)
5. He was forgiving and enjoined righteousness.
Keep to forgiveness (O Prophet) and enjoin what is right, and turn away from the ignorant. (7:199)
6. He was the living clear proof from God.
O mankind! Surely, there has come to you a clear proof (Prophet Muhammad) from your Lord and We have sent down to you a clear light (the Qur’an). (4:174)
7. He was courageous, he aided and fought along his troops.
And (remember) when you did go forth in the morning from your Household to assign to the Muslim believers their positions for the battle, and Allah is All-Hearing, All-Knowing. (3:121)
8. He was sent as a God’s Mercy/Grace unto all Peoples.
And [thus, O Prophet,] We have sent thee as [an evidence of Our] grace towards all the worlds. [21:107]
9. He was compassionate and caring to the people he was sent to, by God.
INDEED, there has come unto you [O mankind] a Messenger from among yourselves: heavily weighs -upon him [the thought] that you might suffer [in the life to come]; full of concern for you [is he, and] full of compassion and mercy towards the believers. [9:128]
10. He was sent by God as a teacher to rectify and refine people.
He it is who has raised among the Gentiles a Messenger, from among themselves, who recites His Verses to them, and purifies them, and teaches them the Book and the Wisdom. And, before that, they had indeed been in manifest error. [62:2]
11. He was sent with guidance and truth from God.
He it is who has sent forth His Messenger with the [task of spreading] guidance and the religion of truth, to the end that He may cause it to prevail over all [false] religion -however hateful this may be to those who ascribe divinity to aught beside God. [9:33]
12. He is the bearer of glad tidings and warner to the Jews and Christians
O followers of the Bible! Now, after a long time during which no Messengers have appeared, there has come unto you [this] Our Messenger to make [the truth] clear to you, lest you say, "No bearer of glad tidings has come unto us, nor any warner ": for now there has come unto you a bearer of glad tidings and a warner -since God has the power to will anything. [5:19]
13. Through his ministry God brings people from the darkness of ignorance into light.
[Through] a Messenger who conveys to you Allah's clear Verses, so that he might take those, who believe and do good deeds, out of darkness into light. Allah will admit the one who believes in Him and does good deeds into Gardens underneath which rivers flow, where such people will remain forever. Allah has surely made excellent provision for such a one. [65:11]
14. He fought in defence and inclined to peace as soon as it was offered
But if they incline to peace, incline thou to it as well, and place thy trust in God: verily, He alone is all-hearing, all-knowing! [8:61]
15. He was of clement nature to his followers.
And it was by God's grace that thou [O Prophet] didst deal gently with thy followers: for if thou hadst been harsh and hard of heart, they would indeed have broken away from thee. Pardon them, then, and pray that they be forgiven. And take counsel with them in all matters of public concern; then, when thou hast decided upon a course of action, place thy trust in God: for, verily, God loves those who place their trust in Him. [3:159]
16. He established God’s message as did Abraham (peace be upon him)
SAY: "Behold, my Sustainer has guided me onto a straight way through an ever-true faith-the way of Abraham, who turned away from all that is false, and was not of those who ascribe divinity to aught beside Him." [6:161]
17. Muhammad (peace be upon him) is one of the Messengers of God
AND MUHAMMAD is only a Messenger; all the [other] Messengers have passed away before him: if, then, he dies or is slain, will you turn about on your heels? But he that turns about on his heels can in nowise harm God - whereas God will requite all who are grateful [to Him].
Thus, naturally the faithful or Muslims are expected to love, honour and respect the Prophet Muhammad (peace be upon him) but this love, honour and respect must never lead to the worship of him beside God Almighty. Although, all Muslims of various denominations agree on this point, unfortunately some Muslims do excessively revere the Prophet (peace be upon him) akin to how some Christian denominations and Catholics revere Mary [Arabic: Maryam] or saints which has no warrant from God’s message. This has been clearly implied by the Prophet himself from God:
Say [O Prophet]: "I am but a mortal man like all of you. It has been revealed unto me that your God is the One and Only God. Hence, whoever looks forward [with hope and awe] to meeting his Sustainer (God) [on Judgment Day], let him do righteous deeds, and let him not ascribe unto anyone or anything a share in the worship due to his Sustainer!" [18:110].
Moreover for Muslims, any traits attributed to Prophet Muhammad (peace be upon him) contrary to the noble characteristics ascribed to him by God Almighty should be discarded if the Quran is to be taken as the Criterion (Arabic: al-Furqaan).
Blessed is He who sent down the Criterion upon His Servant that he may be to the worlds a warner [25:1]
And Allah knows best.
