Jonah
قُل لَّآ أَمْلِكُ لِنَفْسِى ضَرًّا وَلَا نَفْعًا إِلَّا مَا شَآءَ ٱللَّهُ ۗ لِكُلِّ أُمَّةٍ أَجَلٌ ۚ إِذَا جَآءَ أَجَلُهُمْ فَلَا يَسْتَـْٔخِرُونَ سَاعَةً ۖ وَلَا يَسْتَقْدِمُونَ
Say, "I possess not for myself any harm or benefit except what Allah should will. For every nation is a [specified] term. When their time has come, then they will not remain behind an hour, nor will they precede [it]."

وَلِكُلِّ أُمَّةٍ رَّسُولٌ ۖ فَإِذَا جَآءَ رَسُولُهُمْ قُضِىَ بَيْنَهُم بِٱلْقِسْطِ وَهُمْ لَا يُظْلَمُونَ
And for every nation is a messenger. So when their messenger comes, it will be judged between them in justice, and they will not be wronged
وَيَقُولُونَ مَتَىٰ هَـٰذَا ٱلْوَعْدُ إِن كُنتُمْ صَـٰدِقِينَ
And they say, "When is [the fulfillment of] this promise, if you should be truthful?"
قُلْ أَرَءَيْتُمْ إِنْ أَتَىٰكُمْ عَذَابُهُۥ بَيَـٰتًا أَوْ نَهَارًا مَّاذَا يَسْتَعْجِلُ مِنْهُ ٱلْمُجْرِمُونَ
Say, "Have you considered: if His punishment should come to you by night or by day - for which [aspect] of it would the criminals be impatient?"
أَثُمَّ إِذَا مَا وَقَعَ ءَامَنتُم بِهِۦٓ ۚ ءَآلْـَٔـٰنَ وَقَدْ كُنتُم بِهِۦ تَسْتَعْجِلُونَ
Then is it that when it has [actually] occurred you will believe in it? Now? And you were [once] for it impatient
