Muhammad ibn al-Muthanna and Ibn Bashshar narrated to us — and the wording is that of Ibn al-Muthanna — they said: Muhammad ibn Ja'far narrated to us, from Shu'bah, from Qatadah, from Abu al-Hakam, who said: I heard Ibn 'Umar narrating from the Prophet, peace and blessings be upon him, who said: "Whoever keeps a dog — except a dog for farming, livestock, or hunting — one qirat is deducted from his reward every day."
