Surah Al Qalam Tafseer

خَاشِعَةً أَبْصَارُهُمْ تَرْهَقُهُمْ ذِلَّةٌ

Their eyes will be cast down and ignominy will cover them;

means, in the final abode, due to their crimes and arrogance in the worldly life. Thus they will be punished with the opposite of what they did.

وَقَدْ كَانُوا يُدْعَوْنَ إِلَى السُّجُودِ وَهُمْ سَالِمُونَ

they used to be called to prostrate themselves, while they were whole, (and had refused).

When they were called to prostrate in the worldly life, they refused to do so even though they were healthy and secure. Therefore, they will be punished with the lack of ability to do so in the Hereafter. When the Almighty Lord makes Himself visible (before the believers), then the believers will fall down in prostration to Him, but no one of the disbelievers and hypocrites will be able to prostrate. rather, their backs will become one plate. Every time one of them attempts to prostrate, he will bow his neck but will not be able to prostrate. This is just like in the life of this world, when these people were in opposition to what the believers were doing.
