Ruling on intercourse for a traveling couple during the daytime of Ramadan

Question:
Is the expiation obligatory for a traveler if he has intercourse with his wife while traveling and during the month of Ramadan?

Answer:
If they are both traveling, then no. If the man and the woman are both travelers, he is permitted to have intercourse with his wife, just as he is permitted to eat and drink, and she is permitted to eat and drink. The One who permitted him to eat and drink also permitted him to have intercourse. However, if he is traveling and she is resident, he is not permitted to have intercourse with her.
