Bukhari

Abdullah ibn Abbas (may Allah be pleased with them both) said: The meaning of «هباء منثورا‏» is that which the wind brings (such as dust, etc.). By «مد الظل‏» is meant the time from the appearance of dawn until sunrise. The meaning of «ساكنا‏» is always. In «عليه دليلا‏», by «دليل» is meant the rising of the sun. By «خلفة‏» is meant that what cannot be accomplished at night can be completed during the day, and what cannot be accomplished during the day can be completed at night. And Imam Hasan al-Basri said: The meaning of «قرة اعین» is: "Make our wives and children God-fearing, obedient to You." There is nothing that cools the eye of a believer more than seeing his beloved ones engaged in the worship of Allah. And Abdullah ibn Abbas (may Allah be pleased with them both) said: The meaning of «ثبورا‏» is destruction and ruin. Others have said: The word «سعير» is masculine; it is derived from «تسعر»; «تسعر» and «اضطرام» mean the intense burning of fire. «تملى عليه‏» are recited aloud; this is derived from «أمليت» and «أمللت». «الرس» refers to «كان», its plural is «رساس». «كان» means «معدن ما يعبأ‏»; the Arabs say «ما عبأت به شيئا», meaning "I did not care about it at all." The meaning of «غراما‏» is destruction, and Mujahid said: The meaning of «عتوا‏» is mischief. Sufyan ibn ‘Uyaynah said: The meaning of «عاتية‏» is that he did not listen to the treasurer angels.

Narrated Anas bin Malik: A man said, "O Allah's Prophet! Will Allah gather the non-believers on their faces on the Day of Resurrection?" He said, "Will not the One Who made him walk on his feet in this world, be able to make him walk on his face on the Day of Resurrection?" (Qatada, a subnarrator, said: Yes, By the Power of Our Lord!)
