أَثُمَّ إِذَا مَا وَقَعَ ءَامَنتُم بِهِۦٓ ۚ ءَآلْـَٔـٰنَ وَقَدْ كُنتُم بِهِۦ تَسْتَعْجِلُونَ
Asumma izaa maa waqa'a aamantum bih; aaal'aana wa qad kuntum bihee tasta'jiloon
Will you believe in it, when it actually happens?’ It will be said, ‘Now [you believe], when [before] you sought to hasten it?’
Only then, when it has fallen upon you, will you believe in it? Now? When you were the ones demanding it be hastened?
