"Karbila is about 55 miles S.W. of Baghdad on the banks of the Euphrates.... The tomb of Husayn is in the centre of the city, and of his brother Abbas in the S.E. quarter are the chief buildings." (C. R. Markham's "A General Sketch of the History of Persia,' p. 486.) Najaf is revered by the shi'ahs, as it enshrines the tomb of Imam Ali.
