Dua is the weapon of the believer, the essence of belief and the connection between the Creator of the universe and his slaves. One of the treasure of Duas is a pearl, known as Dua-e-Nudba.
It is an important and authentic Dua. It's deep meaning penetrates to the depths of the heart. This is enough proof that these are not the words of an ordinary person. They are uttered by the personality who has connection with the celestial world (Aalam-e-Malakoot).
