حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحِ بْنِ الْمُهَاجِرِ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنِ ابْنِ الْهَادِ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، عَنِ النُّعْمَانِ بْنِ أَبِي عَيَّاشٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ: قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ صَامَ يَوْمًا فِي سَبِيلِ اللَّهِ، بَاعَدَ اللَّهُ، بِذَلِكَ الْيَوْمِ، النَّارَ عَنْ وَجْهِهِ سَبْعِينَ خَرِيفًا " .

Muhammad ibn Rumh ibn al-Muhajir informed us; al-Layth ibn Sa‘d informed us, from Ibn al-Had, from Suhayl ibn Abi Salih, from al-Nu‘man ibn Abi Ayyash, from Abu Sa‘id al-Khudri, who said: The Messenger of Allah (peace and blessings be upon him) said: ‘Whoever fasts one day in the path of Allah, Allah will distance the Fire from his face by seventy years on account of that day.’

The source says seventy autumns; ‘seventy years’ conveys the time expression without changing its measure.
