Sura 68: AL-QALAM (THE PEN) - Juz' 29 - Translation Shakir

وَإِنْ يَكَادُ الَّذِينَ كَفَرُوا لَيُزْلِقُونَكَ بِأَبْصَارِهِمْ لَمَّا سَمِعُوا الذِّكْرَ وَيَقُولُونَ إِنَّهُ لَمَجْنُونٌ ﴿۵۱﴾
And those who disbelieve would almost smite you with their eyes when they hear the reminder, and they say: Most surely he is mad (51)
وَمَا هُوَ إِلَّا ذِكْرٌ لِلْعَالَمِينَ ﴿۵۲﴾
And it is naught but a reminder to the nations (52)
