reward of believers

إِنَّمَا تُنذِرُ مَنِ ٱتَّبَعَ ٱلذِّكْرَ وَخَشِىَ ٱلرَّحْمَـٰنَ بِٱلْغَيْبِ ۖ فَبَشِّرْهُ بِمَغْفِرَةٍ وَأَجْرٍ كَرِيمٍ

You can only warn one who follows the message and fears the Most Merciful unseen. So give him good tidings of forgiveness and noble reward.

يَوْمَ تَرَى ٱلْمُؤْمِنِينَ وَٱلْمُؤْمِنَـٰتِ يَسْعَىٰ نُورُهُم بَيْنَ أَيْدِيهِمْ وَبِأَيْمَـٰنِهِم بُشْرَىٰكُمُ ٱلْيَوْمَ جَنَّـٰتٌ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَـٰرُ خَـٰلِدِينَ فِيهَا ۚ ذَٰلِكَ هُوَ ٱلْفَوْزُ ٱلْعَظِيمُ

On the Day you see the believing men and believing women, their light proceeding before them and on their right, [it will be said], "Your good tidings today are [of] gardens beneath which rivers flow, wherein you will abide eternally." That is what is the great attainment.
