Is it permissible to combine the Friday Prayer and the Asr Prayer while traveling, and if not, how should the combination be performed?

A traveler is not obligated to pray Jumu'ah (Friday prayer), but if he does pray it, it suffices for Dhuhr (noon prayer). As for combining Asr (afternoon prayer) with it, there are two opinions: The first is the permissibility of combining Asr by praying it earlier (jama' taqdim) after Jumu'ah, because Jumu'ah is a substitute for Dhuhr, which can be combined with Asr, and a substitute takes the ruling of what it substitutes. The second opinion is that it is not permissible, because Jumu'ah is associated with being a resident (not traveling), and combining prayers is associated with travel. The preponderant opinion is the first one.
