Hadith 21955

حَدَّثَنَا أَبُو الْوَلِيدُ , وَعَفَّانُ , قَالَا : حدثَنَا عُبَيْدُ اللَّهِ بْنُ إِيَادٍ , حَدَّثَنَا إِيَاد يَعْنِي ابْنَ لَقِيطٍ , عَنْ لَيْلَى امْرَأَةِ بَشِيرٍ , قَالَتْ : أَرَدْتُ أَنْ أَصُومَ يَوْمَيْنِ مُوَاصِلَةً , فَمَنَعَنِي بَشِيرٌ , وَقَالَ : إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنْهُ , وَقَالَ : " يَفْعَلُ ذَلِكَ النَّصَارَى , وَلَكِنْ صُومُوا كَمَا أَمَرَكُمْ اللَّهُ عَزَّ وَجَلَّ , وَأَتِمُّوا الصِّيَامَ إِلَى اللَّيْلِ , فَإِذَا كَانَ اللَّيْلُ فَأَفْطِرُوا " .
The wife of Hazrat Basheer (may Allah be pleased with him), "Laila," says that once I wanted to fast for two consecutive days, but Hazrat Basheer (may Allah be pleased with him) stopped me from doing so and said that the Holy Prophet (peace and blessings be upon him) has prohibited this and said that this is what the Christians do. Rather, you should fast in the manner Allah has commanded you: fast until nightfall, and when night comes, break your fast.
