Is it permissible for a worshiper to attend Friday Prayer at one mosque and then at a second mosque?

Repeating a prayer—Jumu'ah or otherwise—without a valid reason is disliked by some scholars, because if it were legislated, it would be possible to perform the prayer many times, which is disliked. However, repeating the prayer is considered sunnah by some Shafi'is, such as someone who travels and sees the people of a town praying differently, whereas Al-Adhra'i prohibited it.
