قَيِّمٗا لِّيُنذِرَ بَأۡسٗا شَدِيدٗا مِّن لَّدُنۡهُ وَيُبَشِّرَ ٱلۡمُؤۡمِنِينَ ٱلَّذِينَ يَعۡمَلُونَ ٱلصَّٰلِحَٰتِ أَنَّ لَهُمۡ أَجۡرًا حَسَنٗا

Qaiyimal liyunzira ba'asan shadeedam mil ladunhu wa yubashshiral mu'mineenal lazeena ya'maloonas saalihaati anna lahum ajran hasanaa

(He hath made it) Straight (and Clear) in order that He may warn (the godless) of a terrible Punishment from Him, and that He may give Glad Tidings to the Believers who work righteous deeds, that they shall have a goodly Reward,

— Al-Kahf (ٱلْكَهْف), 18:2
