Could you tell me whether we can use deodorant that has alcohol in it?
Answer:
Walaikum assalam,
Yes, because the fatwa is that alcohol from other than grapes, dates, and barley, though haram to consume, is not najis or haram to use.
If you search for “alcohol” at http://www.SunniPath.com, you will find details on this.
Wassalam,
Faraz Rabbani
