Is it permissible to make up more than one day's prayers with a single ablution, and what is the ruling on making up missed prayers while traveling, along with shortening the prayer?

A Muslim may perform as many prayers as they wish with a single ablution, as long as their ablution is not invalidated. Maliki jurists make it easy to make up missed prayers, allowing one to make up two days' worth of prayers each day. A traveler should make up missed prayers according to their ability, and if a prayer was missed while not traveling (in residence), it should be made up in full.
