Zuhri said: The words of Abu Huraira (Allah be pleased with him) were conveyed to Ibn Umar who said: May Allah have mercy upon Abu Huraira;
he owned a field.

حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " مَنِ اتَّخَذَ كَلْبًا إِلاَّ كَلْبَ مَاشِيَةٍ أَوْ صَيْدٍ أَوْ زَرْعٍ انْتَقَصَ مِنْ أَجْرِهِ كُلَّ يَوْمٍ قِيرَاطٌ " . قَالَ الزُّهْرِيُّ فَذُكِرَ لاِبْنِ عُمَرَ قَوْلُ أَبِي هُرَيْرَةَ فَقَالَ يَرْحَمُ اللَّهُ أَبَا هُرَيْرَةَ كَانَ صَاحِبَ زَرْعٍ .
