What is meant by Qaza‘ and how does it occur, what are the proofs of its prohibition, and what is your opinion of those who describe Saudi scholars as rigid in these matters?

Scholars are the best of creation after the prophets and messengers. They are not complex; rather, they are the most open-hearted, broad-minded, pure-hearted, and intelligent of people. Backbiting a scholar is more reprehensible and more forbidden than backbiting a Muslim.
