Pure and Impure Items

Using leather products

Q: I have a watch which has a genuine leather strap. My question is whether it is permissible to wear such watches because we are not aware of whether the animal used for the leather is halaal and has been slaughtered in the halaal way.

Dishwashing tablet containing glycerine and alcohol

Q: Dear respected Mufti Saab, I wanted to ask that if the dishwashing washing tablet contains glycerin along with alcohol (and other impure substances), are dishes that are washed impure. The machine does have a rinse cycle but then the 'rinse aid' that too if it contains glycerin along with alcohol or other impure ingredients, are dishes washed with it impure? According to the website , http://www.info-pg.com, dishwasher tablets and 'rinse aid' products do contain glycerin, alcohol ( not sure if all do but some products that I've checked do).
