‘Abdullah bin ‘Amr bin Al ‘Aas said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: ‘The most beloved fasting to Allah, the Mighty and Sublime, is the fast of Daw peace be upon him. He used to fast one day and not the next. And the most beloved prayer to Allah, the Mighty and Sublime, is the prayer of Dawud, peace be upon him. He used to sleep half the night, stand for one-third of it (in prayer), and sleep for one-sixth of it.” (Sahih).
