Sahih Muslim Book 39, Hadith Number 6723.

Chapter : Pertaining to the words of Allah: “Nay, but verily man is inordinate, because he looks upon himself as self-sufficient”.

Ubayy b. Ka’b reported that the words of Allah, the Exalted and Glorious: “We will, surely, make them taste the lesser punishment before the severer punishment (that haply they may return)” (xxxii. 21) imply the torments of the world. (victory of) Rome, seizing (of the Meccans), or smoke. And Shalba was in doubt about seizing or smoke.
