Question: We live in Australia, a country that clearly admits its secular identity that secures freedom of religion and atheism; nevertheless, the broadcast media, whether television or radio, is clothed in the garb of Judo-Christian values. A simple observer can easily see this. The proportion of Muslims to other inhabitants of the country is one to thirty two.

1- Entering a non-Muslim’s house.
2- Attending their religious ceremonies.
3- Entering into trade partnership with them.

5- Their coming to our places of worship.
6- May they deliver speeches in our Masjids?
7- May they deliver a speech in our celebrations in the lecture room outside the Masjid?
