Musannaf Ibn Abi Shayba 3:5756

Waki’ narrated to us, he said: Shu’bah narrated to us, from a man who is called Shubayl, from Abu Hurrah, who said: I said to Ibn Abbas, "Should I shorten [the prayer] to Ayla?" He said, "Do you go and come back in a day?" I said, "Yes." He said, "No, unless it is in a day that is accessible."
