Is the prayer valid for one who commits major sins?

Question:
May Allah reward you with good and do you well. After this, a message reached the program from Jeddah, sent by one of the listening brothers there, who says Abu Faisal. Abu Faisal asks and says: If a person commits a major sin and continues in this disobedience, is his prayer valid, or is it invalid and not valid? Please inform us, may you be rewarded, may Allah reward you with good.

Answer:
If the major sin takes one out of Islam, such as major shirk (associating partners with Allah), or disbelief that expels one from the religion, then his prayer is not valid, nor are all his deeds, if he has a nullifier of Islam, such as abandoning the prayer intentionally, or if he has something of major shirk, or major disbelief that expels one from the religion, or any nullifier of Islam, then no prayer is valid from him, nor any other deeds. But if the major sin is less than shirk and less than disbelief, such as zina (unlawful sexual intercourse), theft, drinking intoxicants, and the other major sins that are less than shirk and less than disbelief, then this person is considered an open sinner with deficient faith, and his prayer and other acts of worship are valid, because he is a Muslim and a believer with deficient faith, and he is not a disbeliever or one who associates partners with Allah, and his righteous deeds are valid, and he sins and is held accountable for the bad deeds and disobediences, except that he repents to Allah (Glorified and Exalted is He), or Allah forgives him what he committed? Yes.
