Peter is a quiet, unremarkable school pupil. The sixth year pupil enjoys going to school, but for some time a classmate has been making his life in a Winterthur primary school difficult. This is not a matter of the usual teasing, but is, above, a question of religion. Ali (name changed) wants to convince Peter of his religious ideas and convert him to Islam. The teacher's attempts to intervene remain without success, resulting in the sensitive Peter showing psychosomatic reactions.
In the 1st class Peter and Ali get on very well. It was not important that 14 of the 19 school pupils had a Muslim background. But later Ali, whose father is a Muslim priest, to give Peter religious instruction. If he was a Muslim, they could be friends, said Ali, whose zeal became ever more marked as time went on.
Ali made fun of Christianity. How is it possible that Jesus is the son of God, asked Ali maliciously. As the class visited a mosque during religious instruction, Ali demanded that Peter now pray to Allah. One day Ali gave his classmates a religious pamphlet of the German convert and hate preacher Pierre Vogel, who is banned from travelling to Switzerland.
