The Prophet (ﷺ) led us in a prayer and then got up on the pulpit and said, "In your prayer and bowing, I certainly see you from my back as I see you (while looking at you.)"
Sahih al-Bukhari Book 8, Hadith 69
← Previous Hadith Allah's Messenger (ﷺ) said, "Do you consider or see that my face is towards the Qibla? By Allah, neither your submissiveness nor your bowing is hidden from me, surely I see you from my back."

Sahih al-Bukhari Book 8, Hadith 68 Next Hadith → Allah's Messenger (ﷺ) ordered for a horse race; the trained horses were to run from a place called Al-Hafya' to Thaniyat Al-Wada` and the horses which were not trained were to run from Al-Thaniya to the Masjid (mosque of) Bani Zuraiq. The sub narrator added: Ibn `Umar was one of those who took part in the race.
