Did the Prophet (peace and blessings be upon him) shorten and combine prayers during his twenty-day stay in Tabuk, or did he only shorten them?

Question:
And likewise, may Allah preserve you, he asks and says: Did the Messenger (peace and blessings be upon him), during his twenty-day stay in Tabuk, shorten and combine prayers, or is the transmitted ruling that he only shortened them?

Answer:
The transmitted ruling is that he shortened the prayer. Yes. It is reported that he departed and combined prayers in it, and they cited this as evidence for the permissibility of combining for the resident. However, the predominant aspect of his biography (peace and blessings be upon him) and his hadiths is that the one who has not departed does not combine, because there is no need for combining. Combining is for the sake of continuing the journey, so the traveler combines, whereas the one who has not departed has no need for this.
