Even wrongdoing between animals will be recompensed on Judgement Day

The Messenger of Allah ﷺ said: “You will surely give rights back to those entitled to them on the Day of Judgement, until even retaliation is taken for the hornless sheep from the horned sheep.”

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ: «لَتُؤَدُّنَّ الْحُقُوقَ إِلَى أَهْلِهَا يَوْمَ الْقِيَامَةِ حَتَّى يُقَادَ لِلشَّاةِ الْجَلْحَاءِ مِنَ الشَّاةِ الْقَرْنَاءِ».
