(At-Theen) 95 : 6
إِلَّا الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ فَلَهُمْ أَجْرٌ غَيْرُ مَمْنُونٍ

 Except for those who believed and did righteous deeds, then they have an uninterrupted reward

It is told in verse 10: 100 that only with Adhikr – the Permission of the Lord – can anyone become a believer. So, the believers who engage by mind, word, and deed in the mission of propagating Adhikr, which is the only instrument to form belief and the Ticket to reach the Lord in Paradise, aiming to extend the lifespan of the universe, will have immeasurable and uninterrupted reward in Paradise.

That is because, by propagating Adhikr, they are helping the Lord, as explained in verses 22: 40; 47: 7; 61: 14. See explanation 39: 33-34; 84: 25; 98: 7-8.
