وَعَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ صَامَ يَوْمًا فِي سَبِيلِ اللَّهِ بَعَّدَ اللَّهُ وَجْهَهُ عَنِ النَّارِ سَبْعِينَ خَرِيفًا»
Abu Said al-Khudri reported God’s messenger as saying, “If anyone fasts for a day while engaged in jihad, God will remove him* seventy years distance from hell.” *Literally, ‘his face’.
