حَدَّثَنَا يَحْيَى بْنُ يَحْيَى قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ يَزِيدَ بْنِ خُصَيْفَةَ أَنَّ السَّائِبَ بْنَ يَزِيدَ أَخْبَرَهُ أَنَّهُ سَمِعَ سُفْيَانَ بْنَ أَبِى زُهَيْرٍ - وَهُوَ رَجُلٌ مِنْ شَنُوءَةَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ -صلى الله عليه وسلم- - قَالَ سَمِعْتُ رَسُولَ اللَّهِ -صلى الله عليه وسلم- يَقُولُ « مَنِ اقْتَنَى كَلْبًا لاَ يُغْنِى عَنْهُ زَرْعًا وَلاَ ضَرْعًا نَقَصَ مِنْ عَمَلِهِ كُلَّ يَوْمٍ قِيرَاطٌ ». قَالَ آنْتَ سَمِعْتَ هَذَا مِنْ رَسُولِ اللَّهِ -صلى الله عليه وسلم- قَالَ إِى وَرَبِّ هَذَا الْمَسْجِدِ.

As-Sa'ib bin Yazid narrated that he heard Sufyan bin Abi Zuhair, who was a man of Shanu'ah and one of the Companions of the Messenger of Allah (s.a.w), say: "I heard the Messenger of Allah (s.a.w) say: "Whoever keeps a dog that is not used in the farm or herding livestock, one Qirat will be deducted from his good deeds every day." He said: "Did you hear that from the Messenger of Allah (s.a.w)?" He said: "Yes, by the Lord of this Masjid."
