"I asked the Messenger of Allah ﷺ about a lost camel that comes to my cisterns that I have prepared for my own camels - will I be rewarded if I give it some water to drink? He said: Yes, in every living being there is reward.'"
سَأَلْتُ رَسُولَ اللَّهِ ﷺ عَنْ ضَالَّةِ الإِبِلِ تَغْشَى حِيَاضِي قَدْ لُطْتُهَا لإِبِلِي فَهَلْ لِي مِنْ أَجْرٍ إِنْ سَقَيْتُهَا فَقَالَ نَعَمْ فِي كُلِّ ذَاتِ كَبِدٍ حَرَّى أَجْرٌ
