Are the two rak'ahs of the mosque upon returning from travel specific to the Prophet's (peace and blessings be upon him) mosque?

Question:
What Allah willed for you.

Answer:
When he returns to his town, it is a recommended practice (sunnah) for a believer to pray two rak'ahs, or otherwise in the mosque, and then go to his house. Now, if the mosque is crowded? Praise be to Allah, it is not [a problem] for men, because it is a recommended practice (mustahabb). Now, is this specific to the Messenger's (peace and blessings be upon him) mosque? It is specific, [but] it is recommended in all lands, in the entire world.
