Guardianship system has an important place in Islam. No matter how misguided they are, a believer should never ostracize his brothers.

ADNAN OKTAR: The believers are obliged to protect and watch over each other. There is a guardianship system in the Quran. A believer should protect other believers as if they are his own brothers. For example, some people say, "That person is a hypocrite, we should expel him." You cannot banish him on your own account. You must base this upon a revelation. How can you diagnose someone with hypocrisy? Even if that person shows all the signs of a hypocrite, he can be cured of all those signs and find the true way. He might be sick but he can be cured. You have no right to banish him. As long as a person says "Laa ilaaha illaAllah Muhammadan Rasulullah," you cannot exclude him from the guardianship system. You cannot say things such as "Begone, go away to disbelievers." Saying so is unlawful. On one hand you are trying to win people over to the cause of Islam, but on the other hand, you are trying to expel people from it. If you are going to expel people, then why are you trying to win disbelievers over in the first place? Disbelievers say, "I am an atheist, I am a disbeliever" or "I am against Islam." What more do you want? They already stay away from the Islamic community. But if you try to win the disbelievers over, then you should try even harder to win over those you believe to be hypocrites. You can easily commune with such people as they are already among you. No matter how abnormal they behave, how ill-tempered they are, the merit, the reward of trying to win such people over are greater. Expelling them, sending them away is not befitting for a Muslim. People occasionally ask me, "One of our friends is a hypocrite, what should we do?" How do you know? Maybe the person who you believe to be a hypocrite will go to heaven and you will go to hell. How could you be so sure? Did you split his chest open and looked at his heart? Even the prophets do not make such a judgment, so how can you? They make such judgments only based on revelations. Even when people admit to their hypocrisy, the prophets try to put them on the right path rather than expelling them. There is no such thing in Islam as sending people away. Believers should protect-watch over people in any case. Otherwise, there would be no need to communicate with disbelievers to win them over. It would be unnecessary, wouldn't it? Does this sound logical? Besides, the hypocrisy of these people is blatant as they admit it themselves. But those who are suspected to be hypocrites are, at worst, sick. And if they are sick, you cure them. I receive shocking mails from our readers. For example one of them says, "I live in Germany. My brother's wife shows signs of hypocrisy." This person does not know her really well but suspects her of being a hypocrite. Let's assume that she is a hypocrite; then educate her, tell her the truths of Islam, talk to her through verses of the Quran, be patient with her, right? Otherwise,
