It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: The most beloved fasts to Allah Almighty are the fasts of Dawud (peace be upon him), and likewise, the most beloved prayer to Allah Almighty is the prayer of Dawud (peace be upon him). He would sleep for half the night, then stand (in prayer) for one third of the night, and then sleep for the remaining sixth part. He would fast one day and break his fast the next day.
