Yunus - 10:51

أَثُمَّ إِذَا مَا وَقَعَ آمَنْتُم بِهِ آلآنَ وَقَدْ كُنتُم بِهِ تَسْتَعْجِلُونَ
[10:51]
And when it comes to pass, will you believe in it? What! now (you believe), and already you wished to have it hastened on.
"Would ye then believe in it at last, when it actually cometh to pass? (It will then be said): 'Ah! now? and ye wanted (aforetime) to hasten it on!'
Is it (only) then, when it hath befallen you, that ye will believe? What! (Believe) now, when (until now) ye have been hastening it on (through disbelief)?
