Let's start with the popular hadeeth, the first one in Saheeh al-Bukhaari:
Actions are judged/rewarded by their intentions...
Now let's look at some examples:
- A man goes for jihad. But his intention is to travel for marrying a woman (from the hadeeth)
- A youth visits an Islamic lecture but it's because many young girls come there.
- A man is forced to say other than the shahaadah but he does not mean it (Bilaal R.A. was force but he was stronger).
- A man pays a bribe (he only does it to get his passport on time for hajj and not doing so he won't get his passport).
- Your kid needs a cough syrup (but some people use it to get high/drunk).
So you see, everything comes down to your intentions.
Now we see from the various ahadeeth that the Prophet (S) used to like the MUSK perfume. Musk is taken from the Gazelle but due to its cost, it is made today using chemicals.
So if you like musk because it was liked by the prophet (s) you are not committing a sin. But if you do it because you think girls are going to like it, you know the answer by now :)
Then comes the final part of my answer... Some things are made for a specific bad purpose. If for example, you walk on the street, I think you'll instantly know by the smell, if someone is using the so-called perfume. And if you get that smell, what will be your thoughts?
So if something has an intended purpose and that purpose is not good, I think you should avoid it. But if for example, you wear musk and someone is drawn by that smell, it's not your problem. But you must be honest about it. Your niyyah must be pure.
