[Machine] Narrated by the Prophet ﷺ , he said, "Whoever does not spend the night in fasting before the break of dawn, their fasting is not valid." Abu Bakr ibn al-Harith al-Faqih informed us that Abu al-Hasan ad-Daraqutni narrated this hadith, and Abdullah ibn Abbad narrated it from al-Mufaddal through this chain of narrators, and all of them are reliable.
عَنِ النَّبِيِّ ﷺ قَالَ مَنْ لَمْ يُبَيِّتِ الصِّيَامَ قَبْلَ طُلُوعِ الْفَجْرِ فَلَا صِيَامَ لَهُ أَخْبَرَنَا أَبُو بَكْرِ بْنُ الْحَارِثِ الْفَقِيهُ قَالَ قَالَ أَبُو الْحَسَنِ الدَّارَقُطْنِيُّ تَفَرَّدَ بِهِ عَبْدُ اللهِ بْنُ عَبَّادٍ عَنِ الْمُفَضَّلِ بِهَذَا الْإِسْنَادِ وَكُلُّهُمْ ثِقَاتٌ
