KALIMATU ‘L-HAZRAH كلمة الحضرة
The fiat of God, when He said “Be,” and it was created. The word كنkun, is therefore called the Kalimatu ‘l-Hazrah. It occurs in the Qur’an, Surah xxxvi. 82: “His bidding is only when He desires anything to say to it ‘BE’, and it is .” And in about eleven other places.
