"....the veneration of, and pilgrimages to, saints were part of an ancient Jewish tradition." Sharot, Stephen (1976). Judaism: A Sociology. New York: Holmes & Meier Publishers. стр. 42.
"The life of these, mainly Sephardi and Oriental (Mizrahi) communities, is marked by an unself-conscious and unquestioning commitment to deeply rooted values, where legalism often yields to common sense, and mystical piety plays an integral part, visible in such practices as veneration of tombs of patriarchs and saints, often associated with pilgrimage." De Lange, Nicholas (2000). An Introduction to Judaism. Cambridge, England: Cambridge University Press. стр. 69.

„Of saints and sinners: The Islam of the Taliban is far removed from the popular Sufism practised by most South Asian Muslims”. The Economist. 18. 12. 2008. „In its popular form, Sufism is expressed mainly through the veneration of saints...South Asia is littered with the tombs of those saints. They include great medieval monuments, like the 13th-century shrine of Khwaja Moinuddin Chisti, founder of South Asia’s pre-eminent Sufi order, in Ajmer. But for every famous grave, there are thousands of roadside shrines, jutting into Delhi’s streets, or sprinkled across the craggy deserts of southern Pakistan.”

„Sufi Islam”. „Although frequently characterized as the mystical component of Islam, there are also "Folklorist" Sufis, and the "Traditional" Sufis...Sufism is characterized by the veneration of local saints and by brotherhoods that practice their own rituals.”
Kim Murphy (8. 5. 2003). „Saudi Shiites Take Hope From Changes Next Door”. Los Angeles Times. „while most Sunnis view them as fellow, though possibly misguided, Muslims, Shiites are regarded as infidels by the Saudi religious establishment, which adheres to the ultraconservative and austere variation of Sunni faith known as Wahhabism. Saudi religious leaders see the Shiite veneration of saints and shrines, celebration of the prophet Muhammad's birthday and other rituals as sinful.”
