Ibn Jurayj ابن جريج · The Book of Leading the Prayer (Al-Imamah)

"The Messenger of Allah (ﷺ) entered upon us and the only people present were myself, my mother, the orphan and Umm Harh, my maternal aunt. He said: 'Stand up and I will lead you in prayer.' It was not the time for a (prescribed) prayer. And he led us in prayer."

"Prayer in congregation is twenty-five levels better than a prayer offered on one's own."

"I saw Ibn 'Umar sitting in Al-Balat when the people were praying. I said: '0 Abu 'Abdur- Rahman, why are you not praying?' He said: 'I have already prayed, and I heard the Messenger of Allah (ﷺ) say: "Do not repeat a prayer twice in one day."

"The Messenger of (ﷺ) said: 'When you come to pray, do not come rushing; come walking in a dignified manner, and whatever you catch up with, pray, and whatever you miss, make it up."'
