Q 1: I have a store in which I
sell perfumes, watches, make-up, creams,
hair-dryers and ready-made women's clothing which are long and not tight-fitting. My question now is: Are any of these items Haram (forbidden) and should I stop selling them, or can I carry on with my business?
There is nothing to indicate that selling the items you have mentioned is Haram as long as this does not lead to any forbidden actions, such as flirting or joking with women and so on.
May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions.
