And 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, Shu'bah narrated to us, he said: I heard Abu Ishaq say: I heard al-Nu'man ibn Bashir giving a sermon, and he was saying: I heard the Messenger of Allah, peace and blessings be upon him, say: "Indeed, the lightest punishment of the people of the Fire on the Day of Resurrection is a man whose feet are placed upon two embers, from which his brain boils."
