Quran 34:53 — Sheba (Saba')

They have rejected it in the past; they have decided instead to uphold conjecture and guesswork.*

[34:52] They will then say, "We now believe in it," but it will be far too late.

[34:54] Consequently, they were deprived of everything they longed for. This is the same fate as their counterparts in the previous generations. They harbored too many doubts.
