Narrated Umar: The Prophet صلی اللہ علیہ وسلم as saying: When the night approaches from this side and the day retreats on that side, and the sun sets - according to the version of Musaddad - he who fasts has reached the time to break it.

Narrated Abdullah bin Abi Awfa: We went along with the Messenger of Allah صلی اللہ علیہ وسلم while he was fasting. When the sun set, he said to Bilal: Bilal, come down and prepare barley beverage for us. He said: Messenger of Allah, would that you waited for the evening. He said: Come down and prepare barley beverage for us. He said: Messenger of Allah, the say still remains on you (i. e. there remains the brightness of the day). He said: Come down and prepare barley drink for us. So he came down and prepared barley drink. The Messenger of Allah صلی اللہ علیہ وسلم drank it and said: When you see that the night approaches from this side, he who fasts has reached the time to break it ; and he pointed to the east with his finger.
