حَدَّثَنَا زِيَادُ بْنُ أَيُّوبَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا الْوَلِيدُ بْنُ جَمِيلٍ الْفِلَسْطِينِيُّ، عَنِ الْقَاسِمِ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ أَبِي أُمَامَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ لَيْسَ شَيْءٌ أَحَبَّ إِلَى اللَّهِ مِنْ قَطْرَتَيْنِ وَأَثَرَيْنِ قَطْرَةٌ مِنْ دُمُوعٍ فِي خَشْيَةِ اللَّهِ وَقَطْرَةُ دَمٍ تُهَرَاقُ فِي سَبِيلِ اللَّهِ ‏.‏ وَأَمَّا الأَثَرَانِ فَأَثَرٌ فِي سَبِيلِ اللَّهِ وَأَثَرٌ فِي فَرِيضَةٍ مِنْ فَرَائِضِ اللَّهِ ‏"‏ ‏.‏ قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ ‏.‏ ‏

Narrated Abu Umamah: That the Prophet (PBUH) said: "There is nothing more beloved to Allah than two drops and two traces: A teardrop shed out of fear of Allah, and a drop of blood shed in Allah's cause. As for the two traces: A trace resulting in Allah's cause, and and a trace resulting from one of the duties that Allah made obligatory." [Abu 'Eisa said:] This Hadith is Hasan Gharib.
