Surah 6. Al-An'am
Ayah 4 - 6
4 وَمَا تَأْتِيهِم مِّنْ ءَايَةٍ مِّنْ ءَايَـٰتِ رَبِّهِمْ إِلَّا كَانُوا۟ عَنْهَا مُعْرِضِينَ
5 فَقَدْ كَذَّبُوا۟ بِٱلْحَقِّ لَمَّا جَآءَهُمْ ۖ فَسَوْفَ يَأْتِيهِمْ أَنۢبَـٰٓؤُا۟ مَا كَانُوا۟ بِهِۦ يَسْتَهْزِءُونَ
6 أَلَمْ يَرَوْا۟ كَمْ أَهْلَكْنَا مِن قَبْلِهِم مِّن قَرْنٍ مَّكَّنَّـٰهُمْ فِى ٱلْأَرْضِ مَا لَمْ نُمَكِّن لَّكُمْ وَأَرْسَلْنَا ٱلسَّمَآءَ عَلَيْهِم مِّدْرَارًا وَجَعَلْنَا ٱلْأَنْهَـٰرَ تَجْرِى مِن تَحْتِهِمْ فَأَهْلَكْنَـٰهُم بِذُنُوبِهِمْ وَأَنشَأْنَا مِنۢ بَعْدِهِمْ قَرْنًا ءَاخَرِينَ
[4-6] Yet the reaction of the people has been that whenever a Sign from the Signs of their Lord has come to them, they have turned away from it: accordingly, they have rejected as false the Truth that has come to them now. Well, they will receive some news4 about what they have been ridiculing so far. Do they not see that We destroyed before them many a people who were dominant in the world during their time? We had given them such power in the land as We have not given you. We sent down for them abundant rains from heavens and made canals flow beneath them. But (when they showed ingratitude), We destroyed them because of their sins and raised up other people in their place.
4The reference is to the "news" of the successes that were to follow the emigration of the Holy Prophet to Madinah. At the time of this revelation, neither the disbelievers nor the Believers could ever imagine the nature of the "news" they were going to receive. So much so that even the Holy Prophet himself was unaware of the kind of successes the Muslims were going to achieve in the near future.
