Sura 30: AL-ROOM (THE ROMANS) - Juz' 21 - Translation Qarib

كَذَلِكَ يَطْبَعُ اللَّهُ عَلَى قُلُوبِ الَّذِينَ لَا يَعْلَمُونَ ﴿۵۹﴾
As such Allah seals the hearts of those who do not know. (59)
فَاصْبِرْ إِنَّ وَعْدَ اللَّهِ حَقٌّ وَلَا يَسْتَخِفَّنَّكَ الَّذِينَ لَا يُوقِنُونَ ﴿۶۰﴾
Therefore, have patience. The promise of Allah is true. Do not let those who are uncertain make you unsteady. (60)
