Arabic hadith text
أَخْبَرَنَا الْحَسَنُ بْنُ قَزَعَةَ، عَنْ حُمَيْدِ بْنِ الأَسْوَدِ، قَالَ حَدَّثَنَا سُهَيْلٌ، عَنِ النُّعْمَانِ بْنِ أَبِي عَيَّاشٍ، قَالَ سَمِعْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ صَامَ يَوْمًا فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ بَاعَدَهُ اللَّهُ عَنِ النَّارِ سَبْعِينَ خَرِيفًا "
Translation
It was narrated that An-Numan bin Abi 'Ayyash said
"I heard Abu Saeed Al-Khudri say: 'The Messenger of Allah said: Whoever fasts one day in the cause of Allah will separate his face from the fire by (a distance of) seventy autumns."'
