The above mentioned tradition has also been narrated by ‘Amr bin Shu’aib from his father, from his grandfather, from the Prophet ﷺ to the same effect. This version has:

regarding the stray sheep he said: Take it (and keep it with you) till its seeker comes to it.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، ح وَحَدَّثَنَا ابْنُ الْعَلاَءِ، حَدَّثَنَا ابْنُ إِدْرِيسَ، عَنِ ابْنِ إِسْحَاقَ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، عَنِ النَّبِيِّ ﷺ بِهَذَا . قَالَ فِي ضَالَّةِ الشَّاءِ
" فَاجْمَعْهَا حَتَّى يَأْتِيَهَا بَاغِيهَا " .
