Hadith 685:1
'Abd al-Razzaq narrated to us, Sufyan informed us, from 'Abd al-Rahman ibn 'Abis, from 'Abd al-Rahman ibn Abi Layla, from a man among the companions of the Prophet, may Allah bless him and grant him peace, who said: The Messenger of Allah, may Allah bless him and grant him peace, forbade cupping for the fasting person, and continuous fasting (wisal), but he did not declare them unlawful for his companions. They said: "O Messenger of Allah, you practice continuous fasting until the pre-dawn meal (sahar)." He said: "If I practice continuous fasting until the pre-dawn meal, my Lord, the Almighty and Majestic, feeds me and gives me drink."
