The practices built around barakah, especially shrine visitation and the veneration of saints' tombs, have been a persistent point of internal Islamic theological debate rather than a settled consensus; reformist and Salafi currents, drawing on scholars such as Ibn Taymiyyah in the medieval period and revived forcefully by later movements, have argued that seeking barakah at tombs or through relics risks shirk, associating created beings with God's exclusive power to bless, and have at times restricted or destroyed shrine architecture on that basis, most visibly in parts of the Arabian Peninsula. Sufi orders and much of the broader Muslim world have continued the practice regardless, arguing that seeking barakah through a righteous intermediary is intercession, not worship of the intermediary, a distinction with a long history of careful articulation in Islamic jurisprudence.
The word and concept have entered general English usage in a diluted form through contact with Sufi teachers and popular spirituality writing in the twentieth century, sometimes stripped of its specifically Islamic and monotheistic framing and used loosely for "blessing" or "positive energy" in a way that would be unrecognizable to the classical sources. Barakah, as a claim about divine action rather than a measurable physical force, has not been and is not treated within Islamic scholarship as the kind of claim a laboratory experiment could test, and none is asserted here.
