Buying Shares Of A Company With Cocktail Lounges
If the business is not essentially a haram business you can invest. Only the portion of the profit, whatever it is, which comes from the sale of haram products will be haram. The rest of the profit will be halal. Now you have to determine how much it is. If it is negligible you can ignore it, if it is somewhat significant, you can give that amount of haram profit to charity without expecting a reward.
