Sunan an-Nasa'i 1577

Muhammad ibn Salamah and al-Harith ibn Miskin narrated to us; the latter was read to while I listened, and the wording is his. Ibn al-Qasim said: Malik narrated to me, from Ibn Shihab, from Ibn al-Musayyab, from Abu Hurairah, that the Messenger of Allah (peace and blessings be upon him) said: “When you say to your companion, ‘Listen!’ while the imam is delivering the sermon, you have engaged in idle speech.”
