It's not fake.. The Prophet Muhammed was also reported to have said: "Leave whatever your heart rejects." Of course this is not applicable to clear explicit verdicts in the Quran and Hadith but you resort to your heart when something comes up to which you don't know what the fatwa is, or if there was no fatwa at all, like in contemporary issues that come up.
