Arabic hadith text
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ مُسْلِمٍ الْبَطِينِ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ: قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ مَا مِنْ أَيَّامٍ الْعَمَلُ الصَّالِحُ فِيهَا أَحَبُّ إِلَى اللَّهِ مِنْ هَذِهِ الأَيَّامِ ‏"‏ ‏.‏ يَعْنِي الْعَشْرَ ‏.‏ قَالُوا: يَا رَسُولَ اللَّهِ! وَلاَ الْجِهَادُ فِي سَبِيلِ اللَّهِ قَالَ: ‏"‏ وَلاَ الْجِهَادُ فِي سَبِيلِ اللَّهِ. إِلاَّ رَجُلٌ خَرَجَ بِنَفْسِهِ وَمَالِهِ فَلَمْ يَرْجِعْ مِنْ ذَلِكَ بِشَىْءٍ ‏"
