Now I have read that option trading is not allowed in Islam, so I want to know if building such software products for option trading would be Halal or Haram? And salary earned by such work would be Halal according to Islam?
A: Haamidaw wa Musalliyaa
Building such software with the intention that it be used for option trading is not permissible and must be avoided. However, if the software has a dual purpose and can be used for permissible activities, then it is permissible to develop the software and market it for its permissible use. Thereafter, if an individual or company uses it for any impermissible activity, the responsibility of the same will be solely upon the user.
And Allah Ta’ala Knows Best
