According to Dr. Zakir Naik every muslim must be a terrorist.
Zakir Naik is not promoting vigilantism. Vigilantism is not allowed in Islam.
Shaykh Hamza Yusuf said...
Yusuf: I would say that he has no legitimate authority, that an Islamic Jihad can only be declared by legitimate state authority. And this is accepted by consensus. There is no vigilantism in Islam. Muslims believe in state authority. (Source)
We must obey those who are in authority unless it is an order that goes against Islam. This is a command from the Glorious Quran...
Surah 4:59
O ye who believe! Obey God, and obey the Apostle, and those charged with authority among you. If ye differ in anything among yourselves, refer it to God and His Apostle, if ye do believe in God and the Last Day: That is best, and most suitable for final determination.
and authentic hadith...
Saheeh Bukhari
Volume 004, Book 052, Hadith Number 203.
Narated By Ibn 'Umar : The 'Prophet said, "It is obligatory for one to listen to and obey (the ruler's orders) unless these orders involve one disobedience (to Allah); but if an act of disobedience (to Allah) is imposed, he should not listen to or obey it."
Saheeh Muslim
Book 020, Hadith Number 4524.
Chapter : Obedience to the ruler is forbidden in matters sinful, but is otherwise obligatory.
It has been narrated on the authority of Abu Huraira that the Messenger of Allah (may peace be upon him) said: It is obligatory for you to listen to the ruler and obey him in adversity and prosperity, in pleasure and displeasure, and even when another person is given (rather undue) preference over you.
Now of course it is the duty of the police to protect the society from these people but please tell me what is wrong in being a helpful citizen. Now if you were walking down the street and you saw a robber robbing an old lady, are you just going to sit back and watch and say "well that is the police's job". No! You are going to go and help her if your capable of doing so. Us Muslims take pride in doing this.
Yes it is true that the suspect is innocent until proven guilty, but Zakir Naik did not say to terrorize the suspects. He said terrorize the anti social elements! Meaning there is already proof and we already know if that they are bad people.
There is a difference between vigilantism and helping out the police. The police would love it if the citizens could cooperate and assist them in their fight against crime.
Ali Sina then goes on to talk about Muslims being criminals and says that they are the worst in the non Muslim countries. Well Ali Sina did not provide any references or proof to back up his claim, but let me just agree with him for sake of argument. So what is your point Ali? Not all Muslims are perfect. There are black sheep in every community. If there are Muslims committing these acts, then they are sinners and not following Islam. You cannot judge Islam by these people, just like how you cannot judge a car by its driver. So even if what Ali Sina says is true, his argument means nothing.
Then Ali Sina goes on to say that Shirk is worse than murder, rape etc. and therefore non Muslims should also be killed. Yes it is true that Shirk is a greater sin but the punishment for that is not in this world but in the hereafter...
Surah 4:48
Lo! Allah forgiveth not that a partner should be ascribed unto Him. He forgiveth (all) save that to whom He will. Whoso ascribeth partners to Allah, he hath indeed invented a tremendous sin.
Because shirk is the greatest sin, it is the only sin that Allah won't forgive if one has not repented from it.
No where does God command us to kill non Muslims simply because they are non Muslim. As a matter of fact, we Muslims are commanded to realize and acknowledge the fact that there are non Muslims.
Surah 2:256
There is no compulsion in religion. The right direction is henceforth distinct from error. And he who rejecteth false deities and believeth in Allah hath grasped a firm handhold which will never break. Allah is Hearer, Knower.
Surah 109
Say: O disbelievers! I worship not that which ye worship; Nor worship ye that which I worship. And I shall not worship that which ye worship. Nor will ye worship that which I worship. Unto you your religion, and unto me my religion.
Surah 16:125
Invite (all) to the Way of thy Lord with wisdom and beautiful preaching; and argue with them in ways that are best and most gracious: for thy Lord knoweth best, who have strayed from His Path, and who receive guidance.
How can we call non Muslims to Islam with wisdom and beautiful preaching by killing them?
Ali Sina is referring to Surah 9 verse 5, which says that Muslims should kill the disbelievers wherever we find them. But this is only referring to time of war. All you have to do is read the verse before it and after it.
