According to the tradition of the Islam, the prophet Muhammad has two swords. The first was a straight blade sword, common to the period, which is now shown in the Topkapi Palace Museum, Istanbul. The second sword is believed to have a split blade. It was given to Ali, the prophet son in low, who fought with it many great battles and seen great victories. The sword was nicknamed Zulfikar (Lord of cleaving). This sword is lost, and no one really knows what was its shape.
