[20].Surah Taha [Tâ-Hâ]: Ayat 105-107

Ayat 105. And they ask you concerning the mountains, say; "My Lord will blast them and scatter them as particles of dust.

Ayat 106. "Then He shall leave it as a level smooth plain.

Ayat 107. "You will see therein nothing crooked or curved."

[Tafseer] They ask thee concerning the Mountains: say, "My Lord will uproot them and scatter them as dust; In the last verse, it was the deceptiveness and relativity of Time that was dealt with. Here we come to the question of space, solidity, bulk. The question was actually put to the Holy Prophet: what will become of the solid Mountains, or in the English phrase, "the eternal hills'? They are no more substantial than anything else in this temporal world. When the "new world", (13:5) of which Unbelievers doubted, is actually in being, the mountains will cease to exist. We can  imagine the scene of judgement as a level plain, in which there are no ups and downs and no places of concealment. All is straight and level, without corners, mysteries, or lurking doubts. The one word nasafa carries the ideas of (1) tearing up by the roots, (2) scattering like chaff or dust, and (3) winnowing. Its twofold repetition here intensifies the meaning. "He will leave them as plains smooth and level; "Nothing crooked or curved wilt thou see in their place."

Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) recited, "That Day it (the earth) will reveal its news (about all that happened over it of good or evil).'' (99:4). Then he (PBUH) inquired, "Do you know what its news are?'' He was told: "Allah and His Messenger know better". He said, "Its news is that it shall bear witness against every slave man and woman they did on its back. It will say: `You did this and this on such and such day.' Those will be its news.''

[At-Tirmidhi, Hadith # 2429] 

Lesson : as mentioned above in Surah Taha Ayat 107."You will see therein nothing crooked or curved" It has stern warning for people that however they may try to hide their sins from others, they will not be able to save themselves from Allah and His system of accountability. This Hadith makes evident the perfect Omnipotence of Allah by telling us that He will bestow power of speech on the earth and it will bear witness to the acts committed on its surface. Its very easy for us the modern human to understand with technology at its peak, as Hadith says `"You did this and this on such and such day". recording of each action via CCTV and other source of surveillance Camera recording, each and every move made by us, the earth bear witness against us It will say: `You did this and this on such and such day.
