Ubaydullah bin 'Abdullah bin 'Utba عبيد الله بن عبد الله بن عتبة بن مسعود · The Book on Salat (Prayer)

"Allah's Messenger came out to us with his head bandaged from his illness. He prayed Maghrib, reciting (Surat) Al-Mursalat." "He did not pray it again until he met Allah the Might and Sublime."

"I was a companion rider on a female donkey with Al-Fadl. We came while the Prophet and his Companions were performing Salat at Mina." He said: "We dismounted from it and joined the row. The donkey then passed in front of them, and this did not invalidate their Salat."
