إِنَّ هَـذَا الْقُرْآنَ يِهْدِي لِلَّتِي هِيَ أَقْوَمُ وَيُبَشِّرُ الْمُؤْمِنِينَ الَّذِينَ يَعْمَلُونَ الصَّالِحَاتِ أَنَّ لَهُمْ أَجْرًا كَبِيرًا
[17:9]
Surely this Quran guides to that which is most upright and gives good news to the believers who do good that they shall have a great reward.
Verily this Qur'an doth guide to that which is most right (or stable), and giveth the Glad Tidings to the Believers who work deeds of righteousness, that they shall have a magnificent reward;
Lo! this Qur'an guideth unto that which is straightest, and giveth tidings unto the believers who do good works that theirs will be a great reward.
