Malik related to me that he heard Ibn Shihab say, "The stray camels in the time of Umar ibn al-Khattab were numerous and left alone. No one touched them until the time of Uthman ibn Affan. He ordered that they be publicised and then sold, and if the owner came afterwards, he was given their price."  

يَقُولُ كَانَتْ ضَوَالُّ الإِبِلِ فِي زَمَانِ عُمَرَ بْنِ الْخَطَّابِ إِبِلاً مُؤَبَّلَةً تَنَاتَجُ لاَ يَمَسُّهَا أَحَدٌ حَتَّى إِذَا كَانَ زَمَانُ عُثْمَانَ بْنِ عَفَّانَ أَمَرَ بِتَعْرِيفِهَا ثُمَّ تُبَاعُ فَإِذَا جَاءَ صَاحِبُهَا أُعْطِيَ ثَمَنَهَا  

[Machine] He heard Ibn Shihab say that the stray camels in the time of Umar ibn al-Khattab were branded, and their offspring would not be touched until the time of Uthman ibn Affan. Uthman then ordered for their identification and registration, and they were sold. When their owner came, they were given their price.  

أَنَّهُ سَمِعَ ابْنَ شِهَابٍ يَقُولُ كَانَتْ ضَوَالُّ الْإِبِلِ فِي زَمَانِ عُمَرَ بْنِ الْخَطَّابِ ؓ إِبِلًا مُؤَبَّلَةً تَنَاتَجُ لَا يَمَسُّهَا حَتَّى إِذَا كَانَ زَمَانُ عُثْمَانَ بْنِ عَفَّانَ ؓ أَمَرَ بِمَعْرِفَتِهَا وَتَعْرِيفِهَا ثُمَّ تُبَاعُ فَإِذَا جَاءَ صَاحِبُهَا أُعْطِيَ ثَمَنَهَا
