What is the best way to learn about religious matters, and who are the scholars whose knowledge is trustworthy? Does understanding the religion help in answering the questions of the two angels in the grave, and what aids in that?

Understanding the religion and learning the rulings of the Sharia is among the best acts of closeness to Allah. Through knowledge, acts of worship and transactions become sound, and by it, a servant comes to know his Lord and the path to salvation. It is also one of the greatest means of steadfastness when questioned in the grave. To learn what a student of knowledge should begin with and from whom knowledge should be acquired, refer to Fatwas numbered: 123613, 107757, 122356, and 124726.
