سنن أبي داود#1720Sahihحَدَّثَنَا عَمْرُو بْنُ عَوْنٍ، أَخْبَرَنَا خَالِدٌ، عَنْ أَبِي حَيَّانَ التَّيْمِيِّ، عَنِ الْمُنْذِرِ بْنِ جَرِيرٍ، قَالَ كُنْتُ مَعَ جَرِيرٍ بِالْبَوَازِيجِ فَجَاءَ الرَّاعِي بِالْبَقَرِ وَفِيهَا بَقَرَةٌ لَيْسَتْ مِنْهَا فَقَالَ لَهُ جَرِيرٌ مَا هَذِهِ قَالَ لَحِقَتْ بِالْبَقَرِ لاَ نَدْرِي لِمَنْ هِيَ . فَقَالَ جَرِيرٌ أَخْرِجُوهَا فَقَدْ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " لاَ يَأْوِي الضَّالَّةَ إِلاَّ ضَالٌّ " .
Narrated Al-Mundhir ibn Jarir: I accompanied Jarir at Bawazij. The shepherd brought the cows. Among them there was a cow that was not one of them. Jarir asked him: What is this? He replied: This was mixed with the cows and we do not know to whom it belongs. Jarir said: Take it out. I heard the Messenger of Allah (ﷺ) say: No one mixes a stray animal (with his animals) but a man who strays from right path
