وَحَدَّثَنِي مَالِكٌ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، أَنَّ ثَابِتَ بْنَ الضَّحَّاكِ الأَنْصَارِيَّ، أَخْبَرَهُ ‏.‏ أَنَّهُ، وَجَدَ بَعِيرًا بِالْحَرَّةِ فَعَقَلَهُ ثُمَّ ذَكَرَهُ لِعُمَرَ بْنِ الْخَطَّابِ فَأَمَرَهُ عُمَرُ أَنْ يُعَرِّفَهُ ثَلاَثَ مَرَّاتٍ فَقَالَ لَهُ ثَابِتٌ إِنَّهُ قَدْ شَغَلَنِي عَنْ ضَيْعَتِي ‏.‏ فَقَالَ لَهُ عُمَرُ أَرْسِلْهُ حَيْثُ وَجَدْتَهُ ‏.‏

Malik related to me from Yahya ibn Said from Sulayman ibn Yasarthat Thabit ibn ad-Dahhak al-Ansari told him that he had found a camelat Harra, so he hobbled it and mentioned it to Umar ibn al-Khattab andUmar ordered him to make it known three times. Thabit said to him,"That would distract me from the running of my estate." Umar said tohim, "Then let it go where you found it." Translation Not Available
