Human rights in Muslim-majority countries
When the United Nations adopted the Universal Declaration of Human Rights (UDHR) in 1948, Saudi Arabia refused to sign it as they were of the view that sharia law had already set out the rights of men and women. To sign the UDHR was deemed unnecessary. What the UDHR did do was to start a debate on human rights in the Islamic world. Following years of deliberation, the Organisation of the Islamic Conference (OIC) adopted the Cairo Declaration of Human Rights in Islam.
Solitary confinement
In 1949, the Universal Declaration of Human Rights (UDHR) was adopted by the United Nations General Assembly. Although the Declaration is non-binding, the basic human rights outlined within it have served as the foundation of customary international law. The relevance of the Declaration to solitary confinement is found in Article 5, which states that “No one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment." Thus, if solitary confinement is believed to constitute torture or cruel, inhuman, or degrading treatment or punishment, then the country practicing solitary confinement is violating the provisions set by the UDHR.
