The sculpture by the Spanish artist Eugenio Merino “Stairway to Heaven” offended just about everyone. Embassy of Israel in Madrid even expressed formal protest.
According to the artist, however, his intention was to convey the idea of tolerance and appeal to the followers of the three religions to respect one another’s beliefs: Rabbi holds the Koran, a Catholic priest read the Torah and the knelt Muslim has the Bible at his side. Muslims, on the other hand, may as well interpret the sculpture as showing that Islam is at the base of the institute of religion.
In postscript, the blogger on whose page I found the article (in Russian, here,) suggests to add a levitating Buddhist above. Something like this, perhaps, characteristically for Buddhas, defying gravity:
Eugenio Merino is no stranger to a controversy. Among other things, he has been taken to court by the Franco Foundation for works Merino has made using the image of the late authoritarian ruler. His work Punching Franco is a lifelike head of Franco designed to be used as a punchbag; the Franco Foundation says it is “demeaning”.
