The ruling on the prayer of a traveler who intends to complete it and then remembers to shorten it

The questioner : Yes, if a person enters the prayer while traveling and intends to pray four rak'ahs, then remembers that he is a traveler and shortens it, is his prayer valid?

The Shaykh : Yes, because the default for the traveler's prayer is shortening, and it does not require an intention. Shortening for the traveler does not require an intention because it is the default.

The questioner : Years.

The Shaykh : And even if he intended four, as long as he intended four while forgetting and then remembered, he returns to the default. Yes.
