النَّبِيَّ صلى الله عليه وسلم قَالَ " بَيْنَا رَجُلٌ بِطَرِيقٍ، اشْتَدَّ 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 بَلَغَ مِنِّي، فَنَزَلَ الْبِئْرَ، فَمَلأَ خُفَّهُ مَاءً، فَسَقَى الْكَلْبَ، فَشَكَرَ اللَّهُ لَهُ، فَغَفَرَ لَهُ ". قَالُوا يَا رَسُولَ اللَّهِ وَإِنَّ لَنَا فِي الْبَهَائِمِ لأَجْرًا فَقَالَ " فِي كُلِّ ذَاتِ كَبِدٍ رَطْبَةٍ أَجْرٌ ".

Meanwhile he saw a dog panting and lickingmud because of excessive thirst. He said to himself, "This dog is suffering from thirst as I did." So, hewent down the well again and filled his shoe with water and watered it. Allah thanked him for thatdeed and forgave him. The people said, "O Allah's Messenger (ﷺ)! Is there a reward for us in serving theanimals?" He replied: "Yes, there is a reward for serving any animate (living being)."
