Verses 21 and 22 tell us about the great reward and ranks these successful people shall have in the life to come:
يُبَشِّرُهُمْ رَبُّهُم بِرَحْمَةٍ مِّنْهُ وَرِضْوَانٍ وَجَنَّاتٍ لَّهُمْ فِيهَا نَعِيمٌ مُّقِيمٌ ﴿21﴾ خَالِدِينَ فِيهَا أَبَدًا ۚ إِنَّ اللَّـهَ عِندَهُ أَجْرٌ عَظِيمٌ ﴿22﴾
Their Lord gives them the happy news of Mercy from Him, and Pleasure, and of Gardens having an everlasting bliss for them, where they shall dwell forever. Surely, 'it is Allah with whom there is a great reward.
