The Book of As-Saum (The Fasting).
بَابُ وُجُوبِ صَوْمِ رَمَضَانَ:
(1) Chapter. Fasting is obligatory in (the month of) Ramadan.
Hadith 1892
حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا إِسْمَاعِيلُ ، عَنْ أَيُّوبَ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ ، قَالَ : " صَامَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَاشُورَاءَ ، وَأَمَرَ بِصِيَامِهِ ، فَلَمَّا فُرِضَ رَمَضَانُ تُرِكَ " ، وَكَانَ عَبْدُ اللَّهِ لَا يَصُومُهُ ، إِلَّا أَنْ يُوَافِقَ صَوْمَهُ .
Narrated Ibn `Umar: The Prophet observed the fast on the 10th of Muharram ('Ashura), and ordered (Muslims) to fast on that day, but when the fasting of the month of Ramadan was prescribed, the fasting of the 'Ashura' was abandoned. `Abdullah did not use to fast on that day unless it coincided with his routine fasting by chance.
