Imam Ali (AS) was buried in Najaf , in Iraq, and his grave in Najaf was visited by infallible Imams, so there is no question of any other place. Nevertheless, history says that a Sayyed pious person by similar name, Sayyed Ali son of Sayyed Abu Talib (Ali Ibn Abi Talib), was buried in Afghanistan before about five hundred years from now which means 8 to 9 centuries after the martyrdom of Imam Ali (AS) . Muslims of the area saw many blessings from visiting his grave and built on his grave a big Masjid and the whole city then was called Mazar Shareef.
