The Prophet ﷺ said: If anyone leaves an animal at a place of perishing and another man brings it to life, it belongs to him who brings it to life. (Using translation from Abū Dāʾūd 3525)
عَنِ الشَّعْبِيِّ يَرْفَعُ الْحَدِيثَ إِلَى النَّبِيِّ ﷺ أَنَّهُ قَالَ مَنْ تَرَكَ دَابَّةً بِمَهْلَكٍ فَأَحْيَاهَا رَجُلٌ فَهِيَ لِمَنْ أَحْيَاهَا
