There are many religious duties for a Muslim who lives in the West. Being a minority, Muslims living in the West cannot demand for the application of Shari`ah. It is, however, their duty to call the Westerners to Islam. Also, Muslims living in the West can demand that in family affairs like marriage, divorce and estate division, they want Shari`ah to be applied. Furthermore, they can call for anything that benefits the whole society such as banning abortion, homosexuality and lesbianism or the like.
Sheikh Faysal Mawlawi, deputy chairman of the European Council for Fatwa and Research, states that: Being a minority, Muslims living in the West cannot demand for the application of Shari`ah. It is, however, their duty to call the Westerners to Islam. If the number of Muslims there increases, then they may one day be able to call for the application of Islamic Shari`ah.
However, Muslims in the West can demand that in family affairs like marriage, divorce and estate division, they want Shari`ah to be applied, for this is a clear-cut issue relating to human rights that are always championed by Westerners themselves. As we know, one of the unique features of the Muslim state is that, while applying the Islamic Shari`ah in full, it gave the chance to non-Muslims living inside the Muslim state to act in accordance with their own religions in matters relating to family law. However, in other issues, all citizens of the Muslim state are subject to one law based on Shari`ah.
Naturally, a Muslim living in the West can call for anything that benefits the whole society such as banning abortion, homosexuality and lesbianism or the like since such matters are prohibited in Islam and there are people among Westerners themselves calling for banning such matters.
