Sadly the majority of Ulema (whom we call knowledgeable people) are too stubborn when it comes to speaking the truth!
They hide the actual knowledge because what's written in their books by their MURSHIDS or IMAM or Baabay contradicts sahih Ahadith!
They even twist the Ayah or hadith to validate their falsehood/lies!

All we need to do is to open our chest to accept the actual knowledge, so no Alim will ever cheat us in the name of Allah...
