Narrated to us Muhammad ibn al-Muthanna and Muhammad ibn Bashshar, both said: narrated to us Muhammad ibn Ja'far, narrated to us Shu'bah. And narrated to us Abu Bakr ibn Abi Shaybah — and the wording is his — narrated to us Ghandar, from Shu'bah, from Qatadah, from 'Azrah, from al-Hasan al-'Urani, from Yahya ibn al-Jazzar, from 'Abd al-Rahman ibn Abi Layla, from Ubayy ibn Ka'b, regarding the saying of Allah, Mighty and Majestic: "And We will surely let them taste the lesser punishment before the greater punishment" — he said: the calamities of this world, and the Romans, and the assault, or the smoke. Shu'bah is the one who doubted regarding "the assault" or "the smoke."
