۞ لَيْسُوا۟ سَوَآءًۭ ۗ مِّنْ أَهْلِ ٱلْكِتَٰبِ أُمَّةٌۭ قَآئِمَةٌۭ يَتْلُونَ ءَايَٰتِ ٱللَّهِ ءَانَآءَ ٱلَّيْلِ وَهُمْ يَسْجُدُونَ
They are not all alike. Of the People of the Scripture there is a staunch community who recite the revelations of Allah in the night season, falling prostrate (before Him).

Sahih al-Bukhari
Fasting
Chapter: When to break the Saum (fast)?
Narrated `Abdullah bin Abi `Aufa:
We were in the company of the Prophet (ﷺ) on a journey and he was fasting, and when the sun set, he addressed somebody, "O so-and-so, get up and mix Sawiq with water for us." He replied, "O Allah's Apostle! (Will you wait) till it is evening?" The Prophet (ﷺ) said, "Get down and mix Sawiq with water for us." He replied, "O Allah's Messenger (ﷺ)! (If you wait) till it is evening." The Prophet (ﷺ) said again, "Get down and mix Sawiq with water for us." He replied, "It is still daytime."(1) The Prophet (ﷺ) said again, "Get down and mix Sawiq with water for us." He got down and mixed Sawiq for them. The Prophet (ﷺ) drank it and then said, "When you see night falling from this side, the fasting person should break his fast."
