A traitor is one that betrays another's trust or is false to an obligation or duty; malefaction, perfidy, betrayal are the negative qualifications that a portion of the population in any country always suffer from.
GOD DESPISES TRAITORS
… Allah loveth not the treacherous. (8/58)
… Allah loveth not one given to perfidy and crime: (4/107)
Treachery is a capital sin. The treacherous shall be deprived of God's mercy and are doomed to suffer.
THOSE THAT BETRAY THEIR OWN SELVES
Contend not on behalf of such as betray their own souls … (4/107)
nor wilt thou cease to find them- barring a few - ever bent on (new) deceits: (5/13)
God desires that the souls that He has bestowed on man return to him unsoiled. If they commit sins and offenses they do themselves wrong. This is a kind of betrayal to what they have been entrusted with.
TRAITORS ARE DOOMED TO FAIL IN THEIR ATTEMPTS
… Allah will never guide the snare of the false ones. (12/52)
If thou fearest treachery from any group, throw back (their covenant) to them, (so as to be) on equal terms: for Allah loveth not the treacherous. (8/58)
Traitors are the negative forces in nature. As Satan's plots are doomed to failure so shall the traitor's snares.
DON'T BETRAY GOD AND HIS MESSENGER
O ye that believe! betray not the trust of Allah and the Messenger, nor misappropriate knowingly things entrusted to you. (8/27)
"O my Lord! Truly my people took this Qur'an for just foolish nonsense (25/30)
Betrayal of God and of His Messenger is betrayal of the things He has entrusted with man. Sincere believers cannot possibly be traitors. Only the sham believers may be so.
Nature that God had entrusted to the care of man was vitiated and adulterated; the fauna and flora were destroyed; the species of animals became extinct; air was polluted and ecology was disregarded to the point threatening life on earth. The Qur'an is announced to be protected till Doomsday, but the sacred books revealed previous to it were adulterated and destroyed. Israelites have proved to be murderers of prophets among others John the Baptist and Zacharia, and attempted to kill Jesus on the cross. (They have incurred divine displeasure): In that they broke their covenant; that they rejected the signs of Allah. that they slew the Messengers in defiance of right; that they said, "Our hearts are the wrappings (which preserve Allah.s Word; We need no more)";- Nay, Allah hath set the seal on their hearts for their blasphemy, and little is it they believe;- (4/155)
O my Lord! Truly my people took this Qur'an for just foolish nonsense."(25/30)
"He indeed would well-nigh have misled us from our gods, had it not been that we were constant to them!" - Soon will they know, when they see the Penalty, who it is that is most misled in Path! (42/21)
Is it not to Allah that sincere devotion is due? But those who take for protectors other than Allah (say): "We only serve them in order that they may bring us nearer to Allah." Truly Allah will judge between them in that wherein they differ. But Allah guides not such as are false and ungrateful. (39/3)
Then woe to those who write the Book with their own hands, and then say:"This is from Allah," to traffic with it for miserable price!- Woe to them for what their hands do write, and for the gain they make thereby (2/79)
Let us also draw the attention to the additions to the traditions of the Prophet which have adulterated his genuine sayings. The number of such false traditions attributed to Muhammad is innumerable. Scholars like Bukhari, Muslim, Ibn Hanbel and Imam Malik have tried to sort out the likely genuine traditions reducing the number to ten thousand.
There have been divergences of opinions between them. The criterion to follow in spotting those that must most probably be spoken by the Prophet'sa should be to see whether the traditions agree with the Qur'an. If not they may be disregarded.
We must note also that Ali, the Prophet's son-in-law, Ali's spouse and Fatima, his daughter as well as the grandsons, Hasan and Huseyin were all ill treated after the Prophet's demise. (See Öztürk, Kur'an'daki Islam ve Kur'an'ın Temel Buyrukları).
