Qais b. ‘Ubad said:While I was in the mosque in the front row a man pulled me from behind, moved me aside and took my place, with the result, I swear by God, that I did not know what prayers I said. When he had finished I saw that he was Ubayy b. Ka'b. He said,“Young man, God does not wrong you, for this is a charge from the Prophet to us that we should be near him.”He then faced the qibla and said three times,“May ahl al-'aqd perish, by the Lord of the Ka'ba!”Then he said,“I swear by God that I do not grieve for them, but for those they have led astray.”I asked,“Abu Ya'qub, what do you mean by ahl al-'aqd?”* He replied,“The commanders.”* One of the meanings of 'aqd is“responsibility.” The phrase literally means“the people bf responsibility”, i.e. those who are in responsible positions. A chief ruler may be called sahib al-'aqd wal hall, i.e. he who binds and looses. Nasa’i transmitted it.
