What is the optimal sequence for seeking religious knowledge, and what are the recommended books to read in each field?

The first thing a student of knowledge should do is to purify his intention for Allah Almighty in his words and deeds. He should begin with the Book of Allah because it is "the spring of wisdom, the corrector of the tongue, and the rectifier of thoughts." He should also associate with a shaykh who combines knowledge and piety. It is necessary to start with what is most important, then what is important, so you begin with the correct creed, then the rulings of purification and prayer, and other individual obligations.
