18:2
قَيِّمًا لِّيُنۡذِرَ بَاۡسًا شَدِيۡدًا مِّنۡ لَّدُنۡهُ وَيُبَشِّرَ الۡمُؤۡمِنِيۡنَ الَّذِيۡنَ يَعۡمَلُوۡنَ الصّٰلِحٰتِ اَنَّ لَهُمۡ اَجۡرًا حَسَنًاۙ
[He has made it] straight, to warn of severe punishment from Him and to give good tidings to the believers who do righteous deeds that they will have a good reward
