WE RELATE FROM the book of Ibn as-Sunnī from Ibn ‘Abbās 
, who reported that the Messenger of Allah 
used to teach [the Companions] to say for all pains and fevers: “In the name of Allah the Great, we seek protection with Allah the Mighty from the evil of throbbing veins and from the evil of the heat of Hell-Fire.” [1].

Bismi-llāhi-l-Kabīr, na‘ūdhu bi-llāhi-l-‘Aẓīmi min sharri ‘irqin na‘‘ārin wa min sharri ḥarri-n-Nār.
One should recite al-Fātiḥah, Qul Huwa-llāhu Aḥad and al-Mu‘awwidhāt over oneself and then blow onto one’s hands, as was described above. One should also make the du‘ā’ of difficulties mentioned earlier.
