Coming back to 21:107, we must look at this section of Sura Anbiya (roughly from verse 90-112 of chapter on messengers) in light of what Quran kareem says in
2:285 part-2.
Peace to you, peace to all.
p.s. I say peace
=== (I hope you are not as annoyed with this wonderful term as our friend @ RAMPAGE
)
The ayat you quoted is relevant.. and Its assertion is correct.. that all the Prophets.. were equal in their innocence, in their efforts , in their ethics and morals.. in their characters. Indeed.. it would be Kufr if you say (God forbid) that Prophet Issa was lacklustre in his efforts and weak minded in comparison to Prophet Mohammad. You must also refer to the Hadiath in which the Prophet compares himself to the last brick in a house.. of which the rest of the Prophets are all bricks..Which says two things.
1. The prophet was the last in line of these perfect individuals sent to give mankind a guideline; A guideline that was not into different "software" so to speak.. but more expanded and complete(er) versions of the same software...
2. That he is equal in moral and ethical character to all these Prophets.
Now, all these Prophet's have been accorded certain unique characteristics as well. These characteristics are unique to them just as there are different personalities( again, I emphasize the difference between a personality and character.. I like deep thoughtful conversations, you may not.. its personality.. my character would be my behavior both morally and ethically within those conversations..Angels have no personality.. no desires and cravings and preferences and so forth.) .
Accordingly, there are characteristics given to these prophets..
So, Prophet Adam is also known as Safi-Allah(Allah's Choice)..
Prophet Nuh, Naji Allah (Saved of Allah)..
Prophet Ibrahim- Khalil Allah ( friend of Allah)
Prophet Musa(moses) .. Kaleem Ullah (Conversed with God).
Prophet Isa(jesus).. Ruh Allah ( Spirit of God)..interestingly this seems to be a title that may if said during Prophet Issa's time may have led to the concept of the trinity... but that elsewhere
Prophet Muhmammad. - Habib-Allah ( Beloved of God)...
Now, based on that.. these titles are based on what God holds these prophets with him. It does not mean that God did not give his essence to Prophet Moses or Adam or even to us.. but that Prophet Issa had this particular embodiment of God most strong in him.
Now, we all have relatives who are equal in standing to most of us.. correct? for an analogy.. lets say you have twin sons in adulthood. both are of similar features.. both may be very honest and pious . However, one is reserved and intimidating to his peers.. while the other is more outgoing and attracts people. So if you are someone who prefers a certain personality.. even if you give them both equal attention, equal privileged.. etc.. You will still have greater feelings for the one whose personality is what you prefer.
Unlike us however, God is incapable of injustice in dispensing his Love. He does so based on reasons and not out of whim since that would go against his other declared characteristics in the Quran.
Now, Prophet Muhammad was Habib Allah( Beloved of Allah).. in essence, his characteristic.. that is essentially present in all Human beings(including you and me) of being Loved by Allah .. was the strongest of any other creature made by him. Why? If god gave them all equal characters.. and put them on an equal level morally and ethically.. i.e the element of Prophethood.. the mantle.. the identification of it is through the pre-ordained character of these individuals. Since God states that he already has planned what he wishes to happen.. then these characters might have been ordained when he said "Kun". Or perhaps, these characteristics.. of innocence, of Moral and ethical values .. are present due to the Spirit(Ruh) of God in all of us...but I chose to focus on the former for this example.
Then why nominate Prophet Mohammad as his most loved?
All the Prophets were Human beings from different backgrounds.. and different upbringing in many cases.. and different personalities. The characteristics that made them Prophets.. their innocence(of being free from sin),Perfect moral and ethical bounds in their conscious and Their commitment and efforts to preach the message of God are all same and equal. So clearly God has not been unjust to them in their stature as Prophets.
However, their human element.. their personality..their "clay".. the process of how their character encompassed itself.. was different.Perhaps Prophet Moses showed a greater tendency to anger than the others based on the account given of him. Other Prophets have not been narrated to have the same personality.
Hence, the only thing that could distinguish Prophet Mohammad to God as the most beloved seems to be his Personality. Therefore, If the Prophet had a personality(which is a Human condition element) that has been declared by God as his most dear is interpreted by me.. as God's identification of key personality traits that he loves most in a human being. Again, personality.. not capability.
.. not.. features.. not heritage(because otherwise all Prophets should have looked, talked ,walked etc.. in short.. been clones).. not character.. but personality.. (not skills or profession since Moses was a Shephard and Jesus was a Carpenter)
So,if all the Prophets.. are equal in their respect, their capabilities ,their morals and ethics, commitments , etc and this is a direct result of God's command.
And if their human traits are separate from this mantle. Then if God is choosing to call someone his most beloved.. that should in my view embody their characteristic as the best of Human beings. i.e.. with all their inherent limitations(temptations, desires etc).. under immense hardship and trial.. still possessed the best permutation of what ANY human being(as a control).. ANYWHERE(throughout the time and space of humanity) could achieve. And so.. the perfect Human being.
In conclusion, the Prophet was equal in stature, in responsibility, in ethics and morals and so on as I have stated to all these Prophets.. But as a Human being.. he was the perfect example of what we can become as a personality.
Proving or disproving a point has much more weight to it if done in a civil manner.
