"No one feels himself to be immune to hypocrisy except a hypocrite, and no one fears hypocrisy for himself except a believer."
[Muhammad Ibn Abdul Wahab al Wasaabee; "My Home, My Path"]
If you see a hypocrite having followers, then remember that in the time to come there shall be a Dajjaal who too will have amassed followers.
Ibn Al-Jawzee, Kitaab Al-Lataa’if Fil-Waa’iz, p.157.
Shaykh Muhammad ibn Abdul-Wahhaab (rahimahullaah) wrote,
“Know first that if the truth shines forth and is clear, it is not harmed by the large numbers who oppose it and the small numbers who agree with it. You know how some aspects of tawheed have become strange, although they are clearer than the prayer and fasting; and that [strangeness] does not harm it at all.”
[Muallifaat al-Shaykh al-Imam Muhammad ibn Abdul-Wahhaab, vol. 3, section on Fatawa, p. 88]
"A believer searches for the Truth and follows it, while a hypocrite flees from the Truth and rejects it. This hypocrite is the one who claims Islaam - if he does not claim Islaam, he is a disbeliever. But if he is a person who claims Islaam, then we say to him that the way of a Muslim is that he searches for the Truth, pursues it and follows it because of his love for his Religion, while the hypocrite flees from the Truth and if it catches up to him, he rejects it. Claiming Islaam while not acting upon it brings no benefit. People claimed it in the the time of Allaah's Messenger, sallallaahu alayhi wa sallam, and they used to pray with him, fast with him, make hajj with him and fight with him."
