The prohibited perfume

Question: Is it permissible to use the perfumes that are commonly called "cologne" and contain alcohol?

Answer: It is not permissible to use perfume that is called cologne and contains alcohol for it has been medically proved that it causes intoxication for it includes alcohol, so it is Haram (prohibited) for both, men and women to use it.
However , it does not nullify wudu' (ablution) . As for Salah (prayer) its validity is debatable , for the Jumhur (dominant majority of scholars) holds the view that an intoxicant is najis ( ritually impure ) consequently, the Salaf of the one who  offers it while deliberately having Nahasaj (ritual impurity)  on the body and is aware of the ruling is not valid. Some scholars hold the view that the intoxicant does no cause Nahasaj. Thus , it comes to be known that the person who offers Salah with an intoxicant on their clothes or body while forgetting or ignorant of the ruling or thinking that is Tahir ( ritually pure) their Salah is valid. However to be on the safe side, they should wash off what is on their clothes or body in order to avoid the difference in scholars' opinions. If there is a kind of cologne that does not cause intoxication, it is not haram to use it, since the 'Illah (efective cause) given for a ruling exists , the ruling should be applied and vice versa.
May Allah grant us sucess!!!!
