It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) fasted continuously for two days and one night. Then Jibril (peace be upon him) came to him (peace and blessings be upon him) and said: "Indeed, Allah Almighty has accepted your wisal (continuous fasting), and it is not lawful for anyone after you. That is because Allah, the Blessed and Exalted, says: 'Then complete the fast until the night.' So there is no fasting after (the beginning of) the night. And I have been given the command of witr after Fajr."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Thawr except Yahya, and it is not narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) except with this chain."
The text is like this in the printed editions of Dar al-Haramayn and al-Tahhan, whereas in al-Durr al-Manthur the words "wa atimmu" (and complete) are reported.
