Freedom of religion guarantees every person the right to convince or be convinced that a different faith than his own is true; however, some Muslim converts reject the very liberal foundations that allow them to operate freely.
As we see scholars and sheikhs delivering khutbas [sermons] and lectures, writing books to defend Islam, it is no wonder to find lay Muslims practicing da'wa [spreading Islam] while employing wisdom and fair exhortation. Muhammad al-Ghazali (1917-96), a renowned Egyptian religious scholar, a leading figure in the Muslim Brotherhood movement and the head of da'wa for Egypt's ministry of religious endowments, expressed the hope that the hundreds of thousands of Muslim immigrants "will not only maintain their religion, but become pioneers in spreading it, if only the Muslim umma (nation) wished for that and worked for that to happen." Hamdi Hassan, a professor of media studies at al-Azhar University in Cairo, wrote that the Muslim presence in Europe is an example of Muslim proselytizing turning from the defensive mode that characterized it during the eighteenth and nineteenth centuries to a new mode of expansion. In Saudi writings, these notions of proselytizing acquire a militant, confrontational tone. It is the enemy who will attack us and is more dangerous to us. The call on Muslim immigrants to Islamize Westerners finds resonance in some works by Western Muslims.During the 1920s, Saudi scholars protested King 'Abd al-'Aziz Ibn Saud's decision to use wireless communication, claiming it was devilish. The introduction of television broadcasts in the 1960s also caused outrage.The attitude towards the Internet has proved quite different.Muslim scholars have called on immigrant Muslims to become involved in summoning non-Muslims to their faith.Indeed, the call on Muslim migrants to proselytize has become central in contemporary Islamic writings, not only in books, but also in sermons—many online on You Tube—and others on DVDs, and Islamic websites.
