Is it okay to earn money by uploading the content of scholars like Molana Tariq Jameel Bayan or Noman Khan etc on Youtube Or Can I record a Hadith in my Voice by reading it from a book and earn from it through Youtube? And I believe that the Content of Scholars is not Copyright like on different Apps it's Available?
This is more like a juridicial issue. To keep it safe, I'd say send an e-mail to one of them in which you ask their permission to use their content.
But there are 4 main things to take into consideration when taking their content which is written in the Copyright Law of the USA and I think Youtube follows it too:
(1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work
