I heard that if alcohol is found in any item, be it food, medication or toiletry items such as body sprays face creams etc, etc and is extracted from dates or grapes then this is Haram. If so, why is it only dates and grapes?
Al-jawab billahi at-taufeeq (the answer with Allah's guidance)
The alcohol used in perfumes or deodorants is normally a synthetic alcohol, which is not impure (Najis) and will be permissible for external use. However, its oral intake is still impermissible except in the cases of necessary medication.
If the alcohol is from grapes or dates extract, then this will be impure (Najis) and Haram.
Abu Huraira (RadhiAllahu Ta'ala Anhu) reported Allah's Messenger (Sallallahu Alaihi Wasallam) having said: Wine is prepared from the (fruit) of these two trees date-palm and vine. (Muslim, The Book of Drinks)
Ibn 'Umar (RadhiAllahu Ta'ala Anhu), through another chain of transmitters; reported Allah's Messenger (Sallallahu Alaihi Wasallam) having said this: Every intoxicant is Khamr and every intoxicant is forbidden. (Muslim, The Book of Drinks)
