Virtue and merit of a Dur E Najaf, when a person wears a ring of this stone, at his/her every glance towards it, God gives him the reward of Ziyarat, Haj and Umrah, which are kept in his record of action. The reward is equal to the reward of the Prophets and the pious. If God had not been merciful towards the Shias, every gem of Dur E Najaf would have been costly; but Allah made this gem easily available that the poor and rich can wear it alike.
