(Al-Hajj) 22 : 41
الَّذِينَ إِنْ مَكَّنَّاهُمْ فِي الْأَرْضِ أَقَامُوا الصَّلَاةَ وَآتَوُا الزَّكَاةَ وَأَمَرُوا بِالْمَعْرُوفِ وَنَهَوْا عَنِ الْمُنْكَرِ ۗ وَلِلَّهِ عَاقِبَةُ الْأُمُورِ
Those to whom We have given authority in the land, they will establish prayer, give welfare tax, enjoin what is right and forbid what is wrong; and with Allah rests the consequence of every matter.
If there is a group of believers, they will be given the governing power by Lord as told in verse 24: 55. Nobody can make anyone a believer. Only those who utilize Adhikr can become a believer as explained in verses 10: 100 and 108. So the 1 in 1000 believer will propagate Adhikr to entire mankind irrespective of nation or religion for forming the harmony of mankind. He will never try for communal unity and governing power by testifying verses 2: 256 and 4: 118. See explanation 9: 120-121; 16: 110 and 20: 132.
