The Prophet (ﷺ) used to pray facing his camel.
Sunan Abi Dawud Book 2, Hadith 302
← Previous Hadith I saw Sharik who led us in the 'Asr prayer during a funeral ceremony. He placed his cap in front of him, that is, for saying the obligatory prayer the time of which had come.

Sunan Abi Dawud Book 2, Hadith 301 Next Hadith → I never saw the Messenger of Allah (ﷺ) praying in front of a stick, a pillar, or a tree, without having it opposite his right or left eyebrow, and not facing it directly.

Sunan Abi Dawud Book 2, Hadith 303
