Sufyan b. Abu Zuhair (he was a person belonging to the tribe of Shanu'a and was amongst the Conpanions of Allah's Messenger [may peace be upon him ) said: I heard Messenger of Allah ﷺ as saying: He who kept a dog (other than that) which is indispensable for watching the field or the animals would lose one qirat out of his deeds every day. As-Sa'ib b Yazid (one of the narrators) said: Did you hear it from Messenger of Allah ﷺ? He said: Yes. by the Lord of this mosque.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ يَزِيدَ بْنِ خُصَيْفَةَ، أَنَّ السَّائِبَ، بْنَ يَزِيدَ أَخْبَرَهُ أَنَّهُ، سَمِعَ سُفْيَانَ بْنَ أَبِي زُهَيْرٍ، - وَهُوَ رَجُلٌ مِنْ شَنُوءَةَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ - قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " مَنِ اقْتَنَى كَلْبًا لاَ يُغْنِي عَنْهُ زَرْعًا وَلاَ ضَرْعًا نَقَصَ مِنْ عَمَلِهِ كُلَّ يَوْمٍ قِيرَاطٌ " . قَالَ آنْتَ سَمِعْتَ هَذَا مِنْ رَسُولِ اللَّهِ ﷺ قَالَ إِي وَرَبِّ هَذَا الْمَسْجِدِ .
