Riyad as-Salihin 17:259

Jarir bin Abdullah (May Allah be pleased with him) said:

The Prophet (ﷺ) said, "When the slave runs away from his master, his Salat (prayer) will not be accepted." [Muslim] . Another narration is: "He is guilty of disbelief (i.e., in case he believes in the lawfulness of doing so)."
