حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " تَكَفَّلَ اللَّهُ لِمَنْ جَاهَدَ فِي سَبِيلِهِ، لاَ يُخْرِجُهُ مِنْ بَيْتِهِ إِلاَّ الْجِهَادُ فِي سَبِيلِهِ، وَتَصْدِيقُ كَلِمَتِهِ أَنْ يُدْخِلَهُ الْجَنَّةَ، أَوْ يَرُدَّهُ إِلَى مَسْكَنِهِ بِمَا نَالَ مِنْ أَجْرٍ أَوْ غَنِيمَةٍ ".
