Musnad Ahmad 1018:80

Rawh narrated to us, Ibn Jurayj narrated to us, 'Amr ibn Yahya ibn 'Amarah ibn Abi Hasan informed me, Maryam bint Iyas ibn al-Bukayr, a companion of the Prophet (peace and blessings of Allah be upon him), narrated to me, from one of the wives of the Prophet (peace and blessings of Allah be upon him), that the Prophet (peace and blessings of Allah be upon him) entered upon her and said: "Do you have any *dharirah* (fragrant powder)?" She said: "Yes." So he called for it and placed it upon a pimple between his toes. Then he said: "O Allah, Extinguisher of the great and Magnifier of the small, extinguish it from me." And it was extinguished.
