It was narrated to me by Abu al-Tahir and Harmalah; they said: Ibn Wahb informed us; Yunus informed me, from Ibn Shihab, from Sa'id ibn al-Musayyab, from Abu Hurayrah, from the Messenger of Allah (peace and blessings of Allah be upon him), who said: "Whoever keeps a dog that is not a hunting dog, nor a herding dog for livestock, nor a guard dog for land, then two qirats are deducted from his reward every day." And in the hadith of Abu al-Tahir, the phrase "nor a guard dog for land" is not mentioned.
