Book 22: The Book of Fasting Sahih

Chapter 66

If a person did not form the intention of fasting from the night before, can he observe a voluntary fast that day?

باب إِذَا لَمْ يُجْمِعْ مِنَ اللَّيْلِ هَلْ يَصُومُ ذَلِكَ الْيَوْمَ مِنَ التَّطَوُّعِ ‏‏

Sunan an-Nasa'i 2321
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا يَحْيَى، عَنْ يَزِيدَ، قَالَ حَدَّثَنَا سَلَمَةُ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ لِرَجُلٍ ‏ ‏ ‏.‏
"‏ أَذِّنْ - يَوْمَ عَاشُورَاءَ - مَنْ كَانَ أَكَلَ فَلْيُتِمَّ بَقِيَّةَ يَوْمِهِ وَمَنْ لَمْ يَكُنْ أَكَلَ فَلْيَصُمْ ‏"
It was narrated that Yazid said:

"Salamah told us that the Messenger of Allah said to a man: 'Announce the day of Ashura. Whoever has eaten let him not eat for the rest of the day, and whoever has not eaten, let him fast."'
