Quran 20:107 — T.H. (Ta Ha)

"Not even the slightest hill will you see therein, nor a dip."

[20:106] "He will leave them like a barren, flat land.

[20:108] On that day, everyone will follow the caller, without the slightest deviation. All sounds will be hushed before the Most Gracious; you will hear nothing but whispers.
