حَدَّثَنَا مُحَمَّدُ بْنُ عَرْعَرَةَ ، قَالَ : حَدَّثَنَا شُعْبَةُ ، عَنْ سُلَيْمَانَ ، عَنْ مُسْلِمٍ الْبَطِينِ ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ ، عَنْ ابْنِ عَبَّاسٍ ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، أَنَّهُ قَالَ : " مَا الْعَمَلُ فِي أَيَّامٍ الْعَشْرِ أَفْضَلَ مِنْهَا فِي هَذِهِ ، قَالُوا : وَلَا الْجِهَادُ ، قَالَ : وَلَا الْجِهَادُ ، إِلَّا رَجُلٌ خَرَجَ يُخَاطِرُ بِنَفْسِهِ وَمَالِهِ فَلَمْ يَرْجِعْ بِشَيْءٍ " .
Narrated Ibn `Abbas: The Prophet said, "No good deeds done on other days are superior to those done on these (first ten days of Dhul Hijja)." Then some companions of the Prophet said, "Not even Jihad?" He replied, "Not even Jihad, except that of a man who does it by putting himself and his property in danger (for Allah's sake) and does not return with any of those things."
