Indeed, this Qur’an guides to that which is most suitable and gives good tidings to the believers who do righteous deeds that they will have a great reward.
And that those who do not believe in the Hereafter – We have prepared for them a painful punishment.
Chapter 17 Al-‘Isrā : Verses 9-10
Praising the Qur’an
Allah praises His noble Book, the Qur’an, which He revealed to His Messenger Muhammad . It directs people to the best and clearest of ways.
(gives good news to those who believe,) in it
(those who do righteous deeds,) in accordance with it, telling them
(that they will have a great reward,) i.e., on the Day of Resurrection. And He tells
(those who do not believe in the Hereafter,) that
(for them is a painful torment,) i.e. on the Day of Resurrection. As Allah says:
(… then announce to them a painful torment.) (84:24)
