Does a traveler who enters the two sacred sanctuaries leave the regular voluntary prayers?

Question:
If a traveler comes to Makkah or al-Madinah, does he pray the regular voluntary prayers or leave them off, following the Prophet (peace and blessings be upon him)?

Answer:
If he is shortening the prayer, he leaves off the regular voluntary prayers except for the dawn prayer, because he does not shorten the regular voluntary prayers before the dawn prayer, meaning if he is shortening the prayer. But if he is praying the full prayer, he performs the regular voluntary prayers.
