What is the ruling on using perfumes that contain alcohol?

The basic rule for perfumes and fragrances is permissibility, unless a religious impediment is known to be present, such as intoxication or impurity. If it is established that a perfume contains an intoxicant, like the high percentage of alcohol found in cologne, then it must be avoided, based on the Prophet's (peace be upon him) saying: "Whatever intoxicates in large quantities, a small quantity of it is forbidden."
