It is narrated from Hazrat Iyas bin Bukair (may Allah be pleased with him) that once the Holy Prophet (peace and blessings be upon him) went to one of his noble wives and asked her, "Do you have the perfume called 'Dhareerah'?" She replied, "Yes!" The Holy Prophet (peace and blessings be upon him) had it brought and began to apply it to the boils between his toes. Then he made this supplication: "O Allah, the One who extinguishes the big and makes the small big! Remove this boil." Thus, those boils were removed.
