Quran 18, Al-Kahf (The Cave) ⓘ

18:2(But hath made it) straight, to give warning of stern punishment from Him, and to bring unto the believers who do good works the news that theirs will be a fair reward,

قَيِّمًا لِيُنْذِرَ بَأْسًا شَدِيدًا مِنْ لَدُنْهُ وَيُبَشِّرَ الْمُؤْمِنِينَ الَّذِينَ يَعْمَلُونَ الصَّالِحَاتِ أَنَّ لَهُمْ أَجْرًا حَسَنًا
