Nafie' نافع مولى ابن عمر · The Book of the Qiblah

"While the people were in Quba praying Subh prayer, someone came to them and said that revelation had come to Messenger of Allah(ﷺ) the night before, and he had been commanded to face Ka'bah. So face toward it. They had been facing toward Ash-Sham, so they turned to face toward Ka'bah."

It was narrated from Ibn Umar concerning the Messenger of Allah (ﷺ) he said: "He used to set up a short spear then pray facing toward it."
