Hadith 17:801
Ali ibn Mushir narrated to us, from Dawud ibn Abi Hind, from Bakr ibn Abd al-Muzani, from Alqama ibn Abdullah, that Ibn Umar said to a man who spoke to his companion on the day of Friday while the Imam was delivering the sermon: "As for you, you are a donkey; and as for your companion, there is no Friday (prayer) for him."
حدثنا علي بن مسهر عن داود بن أبي هند عن بكر بن عبد المزني عن علقمة بن عبد الله أن بن عمر قال لرجل كلم صاحبه يوم الجمعة والإمام يخطب أما أنت فحمار وأما صاحبك فلا جمعة له
