Throughout a persons life we may encounter situations where we have to make choices and we may not be sure of these choices of being Halal or Haram, we may try and apply logic to apply this through religion but some matters are too complicated and not explicitly mentioned in the Quran and even with the help of scholars, they may produce different opinions which really doesn't provide a solution!

Now would a person who has such a doubtful manner and unsure whether this manner will be halal or haram, what should a person do abandon that manner just in case or follow his instincts?

Or would it be best to seeks Allah's help through Dua and Salat Al Istikhara?
