Guidance that a Muslim should acquire knowledge of Islamic jurisprudence before engaging in acts of worship

Question:
We begin with a letter from Muhammad ibn Nasser al-Salih from al-Qasim. Muhammad says in his letter: We heard in one of the sessions of the program (the program "Light on the Path") by the honorable Shaykh 'Abd al-'Aziz ibn 'Abd Allah ibn Baz, and many of these questions should have been sent by pilgrims, or by Muslims, before they engage in acts of worship, not after they have engaged in them and made mistakes. What is the position of Islam regarding this?
And what is the Shaykh's opinion? May Allah reward us with good for him.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful.
Praise be to Allah, and may Allah send blessings and peace upon the Messenger of Allah, upon his family and his Companions, and upon those who follow his guidance. As for what follows:
This is the obligatory duty. It is obligatory for the Muslim to ask before engaging in acts of worship. He should ask about the matters of his religion and acquire knowledge of his religion before engaging in acts of worship. He should ask about the matters of Hajj before entering the state of ihram, ask about the matters of prayer before starting the prayer, and ask about the matters of fasting before starting the fast, if that is possible. That is, he should not be negligent, but rather he should hasten and rush to ask before working on acts of worship. However, if it happens that he was negligent and lax, and did not ask until after that, there is no blame on him. The important thing is that he learned, just as the Prophet (peace and blessings be upon him) said: And he (peace and blessings be upon him) said: .
So it is obligatory for the people of Islam to learn and acquire knowledge of Islamic jurisprudence before they fall into error in their acts of worship, in their prayer, in their fasting, in their Hajj, in their jihad, and in all their affairs. However, if it happens that he was negligent and asked after he had prayed, meaning about what happened to him in his prayer, or about what happened in his fasting, all of this is seeking knowledge. It is all a specific obligatory duty. Allah said: [al-Nahl: 43] before the act of worship and after it, before engaging in it and after engaging in it. But the fact that he prepares, the fact that he asks before engaging in it, the fact that he prepares himself completely, so that when he starts the act of worship, he performs it with knowledge and insight, this is the obligatory duty, and this is the sound path. Yes.
