Hawzah News Agency (Qom, Iran)­ – If such an act is performed by a righteous slave of God who does not claim to be a Prophet, then it is called a 'charism' (karama).

Evidence of the fact that such righteous slaves of God, other than the Prophets, are also capable of performing extraordinary acts is given for example in the heavenly-sent food that was provided for the Virgin Mary; and in the transportation of the throne of the Queen of Sheba [Bilqis] in a single moment from Yemen to Palestine, an act performed by one of Solomon’s prominent companions, Asif b. Barkhiya. The Qur'an relates both of these incidents. In regard to Mary:

Whenever Zachariah went into the sanctuary where she was, he found that she had food ...(Sura Al 'Imran, III:37)

As for the incident concerning the throne of Queen Bilqis:

One who had knowledge of the Scripture said: I will bring it to thee before thy gaze returneth to thee. (Sura al-Naml, XXVII: 40)
