Answer 2

33:36.  

It is not for a believer, man or woman, when Allâh and His Messenger have decreed a matter that they should have any option in their decision. And whoever disobeys Allâh and His Messenger, he has indeed strayed in a plain error.

Allaah has commanded us to refer matters to His judgement and to establish Sharee‘ah, and He has forbidden us to rule with anything else, as is clear from a number of aayaat in the Qur’aan, such as the aayaat in Soorat al-Maa’idah (5) which discuss ruling according to what Allaah has revealed, and mention the following topics:

The command to rule according to what Allaah has revealed: “And so judge between them by what Allaah has revealed . . .” [aayah 49]

Warning against ruling by other than what Allaah has revealed: “. . . and follow not their vain desires . . .” [aayah 49]

Warning against compromising on any detail of Sharee‘ah, no matter how small: “. . . but beware of them lest they turn you far away from some of that which Allaah has sent down to you . . .” [aayah 49]

Forbidding seeking the ruling of jaahiliyyah, as is expressed in the rhetorical question “Do they then seek the judgement of (the Days of) Ignorance?” [aayah 50]

The statement that nobody is better than Allaah to judge: “. . . and who is better in judgement than Allaah for a people who have firm Faith?” [aayah 50]

The statement that whoever does not judge according to what Allaah revealed is a kaafir, a zaalim (oppressor or wrongdoer) and a faasiq (sinner), as Allaah says: “. . . And whoever does not judge by what Allaah has revealed, such are the kaafiroon.” [aayah 44]; “. . . And whoever does not judge by that which Allaah has revealed, such are the zaalimoon (polytheists and wrongdoers)” [aayah 45]; “. . . And whoever does not judge by what Allaah has revealed (then) such (people) are the faasiqoon (rebellious or disobedient).” [aayah 47].

The statement that it is obligatory for the Muslims to judge according to what Allaah has revealed, even if those who seek their judgement are not Muslim, as Allaah says: “. . . And if you judge, judge with justice between them. . .” [aayah 42]

The Prohibition of Being Loyal Friends with Disbelievers

This Ayah discourages and forbids taking the enemies of Islam and its people, such as the People of the Book and the polytheists, as friends. These disbelievers mock the most important acts that any person could ever perform, the honorable, pure acts of Islam which include all types of good for this life and the Hereafter. They mock such acts and make them the subject of jest and play, because this is what these acts represent in their misguided minds and cold hearts. Allah said;

The Prohibition of Supporting the Disbelievers

Allah prohibited His believing servants from becoming supporters of the disbelievers, or to take them as comrades with whom they develop friendships, rather than the believers. Allah warned against such behavior when He said,

Paying Jizyah is a Sign of Kufr and Disgrace

Fighting the Jews and Christians is legislated because They are Idolators and Disbelievers

Allah the Exalted encourages the believers to fight the polytheists, disbelieving Jews and Christians, who uttered this terrible statement and utter lies against Allah, the Exalted. As for the Jews, they claimed that `Uzayr was the son of God, Allah is free of what they attribute to Him. As for the misguidance of Christians over `Isa, it is obvious. This is why Allah declared both groups to be liars,

Answer 3

This is a question which has been bothering me too. I mean, people say: 'If somebody says that he is a Muslim, then he is a Muslim for me'.

But what are the limits? How far does a person have to stretch before he can be labelled a kafir? What if Salman Rushdie says that he is a Muslim? Shall we swallow that?

What if Mirza Qadyani calls himself a Muslim after abusing the Prophet of Allah, Jesus (A.S), and calling Him a drunkard and a prostitute? As well as abusing Allah? Is he a Muslim?

What does somebody have to do to be declared a kafir, even though he claims to be a Muslim? Or does it not matter at all what he does, as long as he claims to be a Muslim?  

Answer 4

A person who's Kufr is clear & declared by Muslim ulama they r Kafir then he is Kafir but a person who's kufur is unclear or doughted We can say his act is kufr, he should be Kafir but we can't declair him a Kafir.
