Does Islam not teach us to show tolerance for the religions of others?

Answer

There is no tolerance for the beliefs of other religions. While non-Muslims are tolerated and while Islam teaches us to show good conduct towards them, there is no compromise with their religious beliefs and practices. We stay far from their religious customs and do not associate with them in any religious activities. Hospitality and kindness to non-Muslims are separate issues which are permissible and encouraged. Be kind and honest to them. If possible, be helpful. For example, it is not permissible for a Muslim to participate in the funeral service of his non-Muslim relatives, be they parents. But he may financially assist them, and generally be kind to them in worldly matters.
