Well, a mosaic is actually made of many stones put together on a frame. A caliph is a successor to Muslim rule (there are no actual caliphs anymore). An icon would be the correct answer. Jihad is actually a Muslim term for "Holy War", which is why many terror organizations like ISIS and Al Qaeda are called Jihadists.
Religious art or sacred art can be expressed in the form of sculptures, mosaics, motifs on silk, as well as painted religious motifs on the wood - icon. While the sculpture is characteristic of Catholicism and some other Christian churches, icons are characteristic of both Catholicism and Orthodoxy as well as others. These religious motives represent religious people and events are intended to raise the mind to the spiritual level. Mosaic is also a religious image, but composed of many parts that make up a whole, embedded in a fresh plaster on the wall. The caliph and jihad are Islamic terms, and Islam does not allow any imaginative representation of religious people or events, where caliph is a religious leader in the caliphate area, and jihad is Islamic holy war.
