إِلَّا مَنْ خَطِفَ الْخَطْفَةَ ...

Except such as snatch away something by stealing,

means, except for the one among the Shayatin who manages to get something, which is a word he has heard from the heaven. Then he throws it down to the one who is beneath him, who in turn throws it down to the one who is beneath him. Perhaps the flaming fire will strike him before he is able to throw it down, or perhaps he will throw it -- by the decree of Allah -- before the flaming fire strikes him and burns him. So the other devil takes it to the soothsayer, as we have seen previously in the Hadith.

Allah says:

إِلَّا مَنْ خَطِفَ الْخَطْفَةَ فَأَتْبَعَهُ شِهَابٌ ثَاقِبٌ

Except such as snatch away something by stealing, and they are pursued by a flaming fire of piercing brightness.

meaning, shining brightly.

Ibn Jarir recorded that Ibn Abbas, may Allah be pleased with him, said,

"The Shayatin had places where they sat in the heavens listening to what was being revealed by Allah. The stars did not move and the Shayatin were not struck. When they heard the revelation, they would come down to earth and to every word they would add nine of their own. When the Messenger of Allah was sent, if a Shaytan wanted to take his seat in the heavens, the flaming fire would come and would not miss him; it would burn him every time. They complained about this to Iblis, may Allah curse him, and he said, `Something must have happened.' He sent his troops out and they found the Messenger of Allah standing in prayer between the two mountains of Nakhlah.'' -- Waki` said, "This means in the valley of Nakhlah.'' -- "They went back to Iblis and told him about that, and he said, `This is what has happened.'''
