Malik related to me from Yazid ibn Khusayfa that as-Sa'ib ibn Yazid informed him that he heard Sufyan ibn Abi Zuhayr who was from the Azd Shanua tribe and among the companions of the Messenger of Allah, may Allah bless him and grant him peace, speaking with some people who were with him at the door of the mosque. He said, "I heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'If anyone acquires a dog which he does not use as a sheepdog or for hunting, a qirat will be deducted from the reward of his good deeds each day.' " He was asked, "Did you hear this from the Messenger of Allah, may Allah bless him and grant him peace?" He said, "Yes, by the Lord of this mosque."
حَدَّثَنِي مَالِكٌ، عَنْ يَزِيدَ بْنِ خُصَيْفَةَ، أَنَّ السَّائِبَ بْنَ يَزِيدَ، أَخْبَرَهُ أَنَّهُ، سَمِعَ سُفْيَانَ بْنَ أَبِي زُهَيْرٍ، وَهُوَ رَجُلٌ مِنْ أَزْدِ شَنُوءَةَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ يُحَدِّثُ نَاسًا مَعَهُ عِنْدَ بَابِ الْمَسْجِدِ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنِ اقْتَنَى كَلْبًا لاَ يُغْنِي عَنْهُ زَرْعًا وَلاَ ضَرْعًا نَقَصَ مِنْ عَمَلِهِ كُلَّ يَوْمٍ قِيرَاطٌ " . قَالَ آنْتَ سَمِعْتَ هَذَا مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ إِي وَرَبِّ هَذَا الْمَسْجِدِ .
