Q: As Your Eminence presented and many Muslim brothers may share me this understanding; only the callers of falsehood should be prevented, not the callers of AlHaqq (Truth) from whom people could benefit in the field of Da`wah (calling to Islam).
A: Undoubtedly, it is obligatory to prevent those who call to falsehood and trouble the people of goodness and righteousness to the extent that they may be denied access to Masjids (mosques) and consequently many others may be denied access as well. If the people of falsehood are deterred, the way will be wide open for the callers for AlHaqq.
Rulers should stand against the people of falsehood to prevent them from spreading their evil by all possible means, whether they are Communists, idolaters, Christians, innovators, or ignorant of the ruling of the purified Shar` (Law). The Muslim rulers should prevent the abovementioned people of falsehood from spreading their evil and should support the callers for AlHaqq who call people to abide by the Book of Allah and the Sunnah (whatever is reported from the Prophet) and enlighten them about the obligations Allah set upon them and the prohibited acts out of knowledge and point out to them the Right of Allah, people and rulers and Muslim's right towards his fellow Muslims. It is the callers for AlHaqq who should be helped. Then, whoever goes astray and calls for something against the Shar` should be deterred wherever he is.
