﴿ إِنَّ هَٰذَا ٱلْقُرْءَانَ يَهْدِى لِلَّتِى هِىَ أَقْوَمُ وَيُبَشِّرُ ٱلْمُؤْمِنِينَ ٱلَّذِينَ يَعْمَلُونَ ٱلصَّٰلِحَٰتِ أَنَّ لَهُمْ أَجْرًۭا كَبِيرًۭا ﴾
“VERILY, this Qur'an shows the way to all that is most upright, and gives the believers who do good deeds the glad tiding that theirs will be a great reward;”
(Lo! this Qur'an guideth) leads (unto that which is straightest) unto that which is more correct: the testimony that there is no god except Allah; it is also said that this means: unto that which is more plain, (and giveth tidings unto the believers) who are sincere in their faith (who do good works) solely between themselves and their Lord (that theirs will be a great reward) an abundant reward in Paradise.
