Virtue of giving Water to Living Things

سُرَاقَةَ بْنِ جُعْشُمٍ قَالَ سَأَلْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ عَنْ ضَالَّةِ الإِبِلِ تَغْشَى حِيَاضِي قَدْ لُطْتُهَا لإِبِلِي فَهَلْ لِي مِنْ أَجْرٍ إِنْ سَقَيْتُهَا فَقَالَ: نَعَمْ فِي كُلِّ ذَاتِ كَبِدٍ حَرَّى أَجْرٌ

It was narrated that Suraqah bin Ju’shum said: I asked the Messenger of Allah ﷺ about a lost camel that comes to my cisterns (water reservoir) that I have prepared for my own camels – will I be rewarded if I give it some water to drink? He ﷺ said: Yes, in every living being there is reward.
