One part he deposited in the Jami Masjid of Ghazni, one he placed at the entrance of the royal palace, the third he sent to Mecca and the fourth to Medina.

[Among the different coins struck in Mahmud's reign one bore the following inscription:] "The right hand of the empire, Mahmud Sultan, son of Nasir-ud-Din Subuk-Tigin, Breaker of Idols."
