حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرٍ عَنْ أَبِي صَالِحٍ السَّمَّانِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ : " بَيْنَمَا رَجُلٌ يَمْشِي بِطَرِيقٍ فَاشْتَدَّ عَلَيْهِ الْعَطَشُ، فَوَجَدَ بِئْرًا فَنَزَلَ فِيهَا فَشَرِبَ ثُمَّ خَرَجَ فَإِذَا كَلْبٌ يَلْهَثُ يَأْكُلُ الثَّرَى مِنَ الْعَطَشِ، فَقَالَ الرَّجُلُ : لَقَدْ بَلَغَ هَذَا الْكَلْبَ مِنَ الْعَطَشِ مِثْلُ الَّذِي كَانَ بَلَغَنِي، فَنَزَلَ الْبِئْرَ فَمَلأَ خُفَّيْهِ فَأَمْسَكَهُ بِفِيهِ حَتَّى رَقِيَ فَسَقَى الْكَلْبَ، فَشَكَرَ اللَّهُ لَهُ فَغَفَرَ لَهُ " . فَقَالُوا : يَا رَسُولَ اللَّهِ وَإِنَّ لَنَا فِي الْبَهَائِمِ لأَجْرًا فَقَالَ : " فِي كُلِّ ذَاتِ كَبِدٍ رَطْبَةٍ أَجْرٌ " .
Abu Hurairah reported the Apostle of Allaah(PBUH) as saying “ While a man was going on his way, he felt himself thirsty severely. He found a well and e went down in it. He drank water and came out. Suddenly he saw a dog panting and eating soil due to thirst. The man said (to himself) “This dog must have reached the same condition due to thirst as I had reached. So he went down into the well, filled his sock with water, held it with his mouth and came up. He supplied water to the dog. Allaah appreciated this and forgave him.” They asked “Apostle of Allaah(PBUH), Is there any reward for us for these beasts? He replied, For every cool liver there is a reward.” Translation Not Available
