Machine translationRead the Arabic original
Question:
Honorable Shaykh, may Allah grant you success. This questioner says: If a traveler joins a resident imam in a four-rak'ah prayer, is it permissible for him to say the taslim after two rak'ahs and then complete his prayer?
Answer:
It is forbidden for him, and his prayer is invalid. His ruling is the same as the imam's: if the imam completes the prayer, he must complete it with him. If he shortens his prayer behind the imam, his prayer is not valid.
