Surah 10. Yunus
Ayah 48 - 52
48 وَيَقُولُونَ مَتَىٰ هَـٰذَا ٱلْوَعْدُ إِن كُنتُمْ صَـٰدِقِينَ
49 قُل لَّآ أَمْلِكُ لِنَفْسِى ضَرًّا وَلَا نَفْعًا إِلَّا مَا شَآءَ ٱللَّهُ ۗ لِكُلِّ أُمَّةٍ أَجَلٌ ۚ إِذَا جَآءَ أَجَلُهُمْ فَلَا يَسْتَـْٔخِرُونَ سَاعَةً ۖ وَلَا يَسْتَقْدِمُونَ
50 قُلْ أَرَءَيْتُمْ إِنْ أَتَىٰكُمْ عَذَابُهُۥ بَيَـٰتًا أَوْ نَهَارًا مَّاذَا يَسْتَعْجِلُ مِنْهُ ٱلْمُجْرِمُونَ
51 أَثُمَّ إِذَا مَا وَقَعَ ءَامَنتُم بِهِۦٓ ۚ ءَآلْـَٔـٰنَ وَقَدْ كُنتُم بِهِۦ تَسْتَعْجِلُونَ
52 ثُمَّ قِيلَ لِلَّذِينَ ظَلَمُوا۟ ذُوقُوا۟ عَذَابَ ٱلْخُلْدِ هَلْ تُجْزَوْنَ إِلَّا بِمَا كُنتُمْ تَكْسِبُونَ
[48-52] They ask "When will this threat come to pass ? Tell us if what you say be true. " Say "I have no power to bring benefits or to avert evils from myself: everything depends upon Allah's will.57 Every ummat has its appointed term: when that term expires it is neither delayed nor advanced for them by a single hour."58 Ask them "Have you ever considered this? (What can you do to avert it,) if His scourge comes upon you suddenly by night or by day ? Why is it that the criminals are seeking to hasten it?" What! will you believe in it, when it actually overtakes you?-Do you want to escape from it now, when you yourselves were demanding it? Then it will be said to the transgressors, "Now taste the everlasting torment; what other recompense than this do you expect to get for what you have been earning?"
57This is to say, "I never said that I will sit in judgment on you and inflict torment on those who do not believe in me. Therefore, I am not in a position to tell when the threat will be made good. As the threat has been held out by Allah, He will pass His judgment on you when He wills, and in whatever way He wills, for everything depends on His will."
58That is, "Allah passes His judgment on individuals and communities after the expiry of the term that He Himself has set and He alone knows how long it lasts for a community. He is not hasty in giving rewards or punishments. When He sends His Messenger to deliver His Message, He allows sufficient time to each individual and to each community to consider it and ponder over it and mend his (or its) way, during the appointed term. The period of the term may extend to centuries in the case of a community and He knows best how long it should be.
When that term, which is based on justice, expires, and that person or community does not repent of its rebellious conduct, then Allah passes His judgment. When the time of the judgment comes it is neither advanced nor delayed even by a single hour. "
