Qatada قتادة · The Book on Fasting

Zaid bin Thabit said: "We ate Sahar with the Messenger of Allah, then we stood for the Salat." I (Anas) said: "How long was that?" He said: "About the lengthy of fifty Ayahs."

the Messenger of Allah said: "Partake of Sahar, for indeed there is a blessing in the Sahar."

"Whoever eats or drinks forgetfully, then he has not broken (the fast), for it was only a provision that Allah provided for him."

the Prophet said: "There are no days more beloved to Allah that He be worshipped in them than the ten days of Dhul-Hijjah, fasting every day of them is the equivalent of fasting a year, and standing every night of them (in prayer) is the equivalent of standing on the Night of Qadr."

the Messenger of Allah said: "Do not perform Wisal" They said: "But you perform Wisal O Messenger of Allah." He said: "I am not like you are, indeed my Lord feeds me and gives me to drink."
