Ubaidullah bin 'Umar bin Hafs عبيد الله بن عمر بن حفص بن عاصم · The Book on Salat (Prayer)

Allah's Messenger said: "If it were not that it would be a hardship on my Ummah, then I would have ordered you to delay Isha until the third of the night, or its half."

Allah's Messenger said: "Salat in congregation is twenty-seven degrees more virtuous than a man's Salat alone."

"When the Prophet would sit during the Salat, he would place his right hand on his knee, and raise his finger, the one that is next to the thumb, supplicating with it, and his left hand was spread flat on his left knee."

"Allah's Messenger entered the Masjid, and a man entered and offered Salat. Then he came to give Salam to the Propet. He returned the Salam to him and said: 'Go back and perform Salat, for indeed you have not prayed.' So the man returned to pray as he had prayed. Then he came to give Salam to the Prophet. He returned Salam to him, then : 'When you stand for Salat then say the Takbir, then recite what is easy…

"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."

The Prophet (S) said: "The most virtuous prayer of yours is in your homes, except for the obligatory."
