Surah 37. As-Saffat
Ayah 167 - 173
167 وَإِن كَانُوا۟ لَيَقُولُونَ
168 لَوْ أَنَّ عِندَنَا ذِكْرًا مِّنَ ٱلْأَوَّلِينَ
169 لَكُنَّا عِبَادَ ٱللَّهِ ٱلْمُخْلَصِينَ
170 فَكَفَرُوا۟ بِهِۦ ۖ فَسَوْفَ يَعْلَمُونَ
171 وَلَقَدْ سَبَقَتْ كَلِمَتُنَا لِعِبَادِنَا ٱلْمُرْسَلِينَ
172 إِنَّهُمْ لَهُمُ ٱلْمَنصُورُونَ
173 وَإِنَّ جُندَنَا لَهُمُ ٱلْغَـٰلِبُونَ
[167-173] Before this they used to say, "If we had the 'Admonition' which the earlier people had received, we would have been the chosen servants of Allah."92 But (when it did come) they denied it. Now, they will soon come to know (the consequences of this attitude). We have already promised Our servants whom We sent that they would certainly be helped, and Our army alone would be triumphant.93
92This same thing has already been mentioned in Surah Fatir: 42 above.
93"Allah's army": implies the believers who obey Allah's Messenger and side with him. This also includes those unseen powers by which Allah helps the followers of the truth.
This help and domination does not necessarily mean that in every age every Prophet of Allah and his followers must attain political dominance, but this dominance has many forms, one of which is political rule as well. Wherever the Prophets of Allah did not attain any such dominance, they did establish their moral superiority even in those places. The nations which did not accept their message and adopted a way contrary to their teachings, were ultimately doomed to destruction. Whatever philosophies of error and misguidance the people invented and whatever corrupt and evil practices of life they, enforced died out ultimately after they had their sway for some time. But the truths preached by the Prophets of Allah for thousands of years have been unalterable before as they are unalterable today. No one has been able to disprove them in any way.
