Arabic (Original)
حَدَّثَنَا إِسْحَاقُ أَخْبَرَنِي مَالِكٌ عَنْ سُمَيٍّ عَنْ أَبِي صَالِحٍ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَيْنَمَا رَجُلٌ يَمْشِي وَهُوَ بِطَرِيقٍ إِذْ اشْتَدَّ عَلَيْهِ الْعَطَشُ فَوَجَدَ بِئْرًا فَنَزَلَ فِيهَا فَشَرِبَ ثُمَّ خَرَجَ فَإِذَا كَلْبٌ يَلْهَثُ يَأْكُلُ الثَّرَى مِنْ الْعَطَشِ فَقَالَ لَقَدْ بَلَغَ هَذَا الْكَلْبَ مِنْ الْعَطَشِ مِثْلُ الَّذِي بَلَغَنِي فَنَزَلَ الْبِئْرَ فَمَلَأَ خُفَّهُ مَاءً ثُمَّ أَمْسَكَهُ بِفِيهِ حَتَّى رَقِيَ بِهِ فَسَقَى الْكَلْبَ فَشَكَرَ اللَّهُ لَهُ فَغَفَرَ لَهُ قَالُوا يَا رَسُولَ اللَّهِ وَإِنَّ لَنَا فِي الْبَهَائِمِ لَأَجْرًا فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي كُلِّ ذَاتِ كَبِدٍ رَطْبَةٍ أَجْرٌ.
English Translation
The Messenger of Allah (peace be upon him) said: 'While a man was walking on a road, he became very thirsty. He found a well and went down into it and drank. Then he came out, and there was a dog panting and eating mud from thirst. The man said: This dog is suffering from the same thirst I suffered from. So he went down into the well, filled his shoe with water, then held it in his mouth and climbed up, and gave the dog water to drink. Allah thanked him for that and forgave him.' They said: 'O Messenger of Allah, do we get reward for treating animals well?' The Messenger of Allah (peace be upon him) said: 'In every creature with a moist liver (i.e., every living being) there is reward.'
