Fatwa: "It Is Not Permissible ... to Drive Christians to Their Churches"

Source: WikiIslam, Translated from the original Arabic by Al Mutarjim.

In the wake of the Alexandria bombing, here comes this fatwa from the highly-popular Islamic website Islamweb.net ruling that Muslims are not allowed to drive Christians to church, as that is tantamount to "support[ing] them in their vain and perverted rites and religion." 

Question: A bus driver occasionally drives Christians to their churches to perform religious rites. He then goes to the mosque and performs his prayers. When they finish their rites, he drives them back home. Of course he doesn't always do this, but he does do it sometimes. At times he also drives Christian dance teams, who are performing some rites associated with Christian holidays. What is the ruling on all of this? Fatwa: Praise be to Allah, and prayers and peace be upon the prophet of Allah, and on his family and companions, etc.

It is not permissible for this man to drive Christians to their churches, nor to drive those who dance on their holidays. For if the Christians are confessing their religion, it is not permissible to support them in their vain and perverted rites and religion. This is according to the saying of the Most High: "Help ye one another in righteousness and piety, but help ye not one another in sin and rancour" [Qur'an 5:2]. This is the general view, which is contrary to the view of the Hanafis, who hold that it is permissible to do such things for employment. [...]

Ruling on transporting Christians to their churches
Islamweb, Fatwa No. 147523, January 19, 2011

According to this Fatwa, a Muslim driver is not permitted to drive Christians to their churches, nor to any of their activities.  It is strictly forbidden for a Muslim to do that because our Christian religion and rites are "vain and perverted."
