[Machine] "The fasting person is not harmed by eating at night, but rather by eating during the day. For indeed, the moisture of the fasting person's lips is a light between their eyes on the Day of Judgment."  

البيهقي:٨٣٣٤ – أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللهِ الْحَافِظُ ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ قَالَ سَمِعْتُ الْعَبَّاسَ بْنَ مُحَمَّدٍ يَقُولُ سَمِعْتُ يَحْيَى بْنَ مَعِينٍ يَقُولُ ثنا عَلِيُّ بْنُ ثَابِتٍ عَنْ كَيْسَانَ أَبِي عُمَرَ عَنْ يَزِيدَ بْنِ بِلَالٍ مَوْلَاهُ وَكَانَ قَدْ شَهِدَ مَعَ عَلِيٍّ صِفِّينَ عَنْ عَلِيٍّ ؓ قَالَ

لَا يَسْتَاكُ الصَّائِمُ بِالْعَشِيِّ وَلَكِنْ بِاللَّيْلِ فَإِنَّ يُبُوسَ شَفَتَيِ الصَّائِمِ نُورٌ بَيْنَ عَيْنَيْهِ يَوْمَ الْقِيَامَةِ
