ROOT ر ك م

3:180.

Commentary:

The words, separate the bad from the good, refer to the first part of the previous verse, giving the reason for the defeat and failure of the disbelievers. God would cause their war against Islam to end in their defeat so that He might distinguish the righteous from the unrighteous. Similarly, the latter part of this verse, viz. put the bad, one upon another, and heap them up all together, and then cast them into Hell, corresponds to the latter part of the previous verse, viz. that the disbelievers shall be gathered into Hell. The words, heap them up all together, imply that as the disbelievers made a common cause against Islam, they would, as it were, all be heaped up into a bundle and then thrown into the fire of Hell as one huge piece of fuel.

46:25.

Commentary:

In the two previous verses disbelievers were warned that Divine punishment was about to overtake them. But such is their state of utter heedlessness and false sense of security (says the verse) that they do not benefit by the timely Divine warning, so that even if they see a piece of the sky actually falling upon them, they would deceive themselves by considering it as a piece of God’s mercy in the form of 'piled-up clouds.' The disbelievers go so far as to challenge the Prophet to "cause a portion of the sky to fall upon us if thou art truthful" (26:188).
