Surat Yunus (47-48)

{وَلِكُلِّ أُمَّةٍ رَّسُولٌ فَإِذَا جَاء رَسُولُهُمْ قُضِيَ بَيْنَهُم بِالْقِسْطِ وَهُمْ لاَ يُظْلَمُونَ} (يونس: 47)

47- For every nation there will be a Messenger to whom they shall be ascribed and attributed on the Day of Recompense and he shall accompany them in the time of reckoning. So, when the messenger of each nation arrives at the gathering place to testify against them with justice, the believers shall survive, whereas disbelievers shall be punished. No one shall suffer injustice, no one shall be tortured for the sins of others, and their good deeds shall never be reduced.

{وَيَقُولُونَ مَتَى هَـذَا الْوَعْدُ إِن كُنتُمْ صَادِقِينَ} (يونس: 48)

48- Polytheists said to you as if they were hastening torment: When is the time of torment which you promised us, O Muhammad, if you and your Companions are truthful?
