Ayoub al-Sakhtiyani أيوب السختياني · The Book of Fasting

'When it is Ramadan, the gates of Paradise are opened, the gates of Hell are closed, and the devils are chained up."' It was narrated by Ibn Ishaq from Az-Zuhri.

"I came to the Messenger of Allah from a journey and greeted him with Salam. When I was going to leave he said: 'Stay and have meal for breakfast, O Abu Umayyah.' I said: 'I am fasting, O Prophet of Allah.' He said: 'Come and I will tell about the traveler. Allah, most high, has waived fasting and of the prayer for him."'

That he came to Prophet, and he mentioned something similar.

he came to the Messenger of Allah from a journey and he said: "Come and have a meal for breakfast, O Abu Umayyah." I said: 'I am fasting; He said: 'Come close and I will tell you about the traveler. Allah, most high, has waived fasting and half of the prayer for him."'

"The Messenger of Allah said: 'The most beloved fasting to Allah, the mighty and sublime, is the fast of Dawud, 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."'
