Practice Relating to Rule 104. Respect for Convictions and Religious Practices
Sweden’s IHL Manual (1991) considers that the fundamental guarantees for persons in the power of one party to the conflict as contained in Article 75 of the 1977 Additional Protocol I are a part of customary international law. 
Sweden, International Humanitarian Law in Armed Conflict, with reference to the Swedish Total Defence System, Swedish Ministry of Defence, January 1991, Section 2.2.3, p. 19.
The manual provides: “As a general rule, civilians within an occupied area shall, as protected persons, under all circumstances enjoy respect as to … religious convictions and practice”. 
Sweden, International Humanitarian Law in Armed Conflict, with reference to the Swedish Total Defence System, Swedish Ministry of Defence, January 1991, Section 6.1.3, p. 122.
The manual also provides:
Occupation shall not involve any change in the faith and religious practice of the population. The IV Geneva Convention contains a number of articles providing protection for religion, faith and religious practices, without this being linked to any particular confession.
