A gyuidance for how to judge between non-Muslims?

(They like to) listen to falsehood, to devour anything forbidden. So if they come to you (O Muhammad SAW), either judge between them, or turn away from them. If you turn away from them, they cannot hurt you in the least. And if you judge, judge with justice between them. Verily, Allâh loves those who act justly.

Al maeda 42

we should not engriefed by the democrats

O Messenger (Muhammad SAW)! Let not those who hurry to fall into disbelief grieve you, of such who say: "We believe" with their mouths but their hearts have no faith. And of the Jews are men who listen much and eagerly to lies - listen to others who have not come to you. They change the words from their places; they say, "If you are given this, take it, but if you are not given this, then beware!" And whomsoever Allâh wants to put in Al¬Fitnah [error, because of his rejecting the Faith], you can do nothing for him against Allâh. Those are the ones whose hearts Allâh does not want to purify (from disbelief and hypocrisy); for them there is a disgrace in this world, and in the Hereafter a great torment.

Comments
Same is the situation of democrats ruling the Islamic countries.They have imposed their own laws and changed it.This may be a point towards Wahhabis who reject the ideas of those who dont follow them and declare them as Mushrik.Each and everything has been made clear by Quran,we just need to poner upon its verses.

Punishment for theft

And (as for) the male theif and the female thief, cut off (from the wrist joint) their (right) hands as a recompense for that which they committed, a punishment by way of example from Allâh. And Allâh is All-Powerful, All-Wise.

Proof of intercession from Quran

O you who believe! Do your duty to Allâh and fear Him. Seek the means of approach to Him, and strive hard in His Cause (as much as you can). So that you may be successful

Al maeda 35

punishment for those who wage war against Allah and His messenger

The recompense of those who wage war against Allâh and His Messenger and do mischief in the land is only that they shall be killed or crucified or their hands and their feet be cut off from the opposite sides, or be exiled from the land. That is their disgrace in this world, and a great torment is theirs in the Hereafter.

Al maeda 33

Deen e Hanif (Islam) has always been provoking the value of a human being

Because of that We ordained for the Children of Israel that if anyone killed a person not in retaliation of murder, or (and) to spread mischief in the land - it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind. And indeed, there came to them Our Messengers with clear proofs, evidences, and signs, even then after that many of them continued to exceed the limits (e.g. by doing oppression unjustly and exceeding beyond the limits set by Allâh by committing the major sins) in the land!

al maeda 32

If you commit a sin,seek repentance and dont mention it openly

Then Allâh sent a crow who scratched the ground to show him to hide the dead body of his brother. He (the murderer) said: "Woe to me! Am I not even able to be as this crow and to hide the dead body of my brother?" Then he became one of those who regretted.
