Sufyan bin Wky' bin al-Jrah سفيان بن وكيع بن الجراح · The Book on Salat (Prayer)

Allah's Messenger said: "the key to Salat is the purification, its Tahrim is the Takbir, and its Tahlilis the Taslim, and there is no Salat for one who did not recite Al-Hamd and a Surah in the obligatory (prayer) or other prayers."

the Prophet said: "The Salat in Masjid Quba is like Umrah."

"The Prophet performed Salat towards his she-camel, or his mount, and he would perform Salat while on his mount, whichever direction it was facing."
