The Messenger of Allah (s.a.w.s.) used to carry this Dua in battles and in all difficulties. The companions asked: O Messenger of Allah (s.a.w.s.), what is the reward of this supplication for one who carries it and one who recites it? And what calamites and problems would be deflected by it?
The Prophet (s.a.w.s.) said: O companions, indeed this supplication is the crown supplication and as for its acceptance, some people have named it the mediation of the prophets. One who carried it achieved bounties. This supplication benefits, by the leave of Allah, against the evil eye and anxiety, and fever, migraine, throbbing ache, and epidemics, and love and obedience, and entry to the rulers, kings, ministers, judges and governors, trustees and the government officers, and the ransom of slaves and insomnia, and difficulty of childbirth. It is beneficial for backache, suffocation (pressure) of the chest, and journey on the land and the sea and for the women who are pregnant, and for peace between man and wife and for joining the iron and for the reining of wolf, and the barking of dog, and the seeking of sustenance and the sorrowful souls, and for separation and blood and from the snakes and the scorpion and from the trampling of Jinn and the trampling of Satans and the plans of the enemies and the greedy ones, and for nullification of magic and plots and defrauding and if it is hung on a tree it will become fruitful by the leave of Allah and if it is hung on the domestic quadruped it would be safe from beasts and wolves, by the leave of Allah.
The Messenger of Allah (s.a.w.s.) said: One who carries it for forty days would be cured and he said: O companions, verily Allah, Gloried and the High, in it has bestowed to Sulaiman bin Dawood the kingdom of the world and in it bestowed to Prophet Yusuf kingdom of Egypt and in it helped Ali bin Abi Talib in exterminating the infidels and helped Muhammad al-Mustafa on the day of the confederation and in it the iron softened for Dawood.
It is also good for business, and you who carries my book I have sealed it by the seal of Allah, Who created the heavens and the earth, by the seal (ring) of Sulaiman bin Dawood by which he secured submission of Satans and men by this writing. The Messenger of Allah (s.a.w.s.) said: Congratulations to one who carries it and woe to the one who denies and falsifies it; and the supplication is as follows:
