(Al-Qalam) 68 : 51
وَإِنْ يَكَادُ الَّذِينَ كَفَرُوا لَيُزْلِقُونَكَ بِأَبْصَارِهِمْ لَمَّا سَمِعُوا الذِّكْرَ وَيَقُولُونَ إِنَّهُ لَمَجْنُونٌ
And when you make hear Adhikr to those who disbelieved, they will surely stare at you with their sights as if they can melt you, and will say: he is a Jinn affected man.
Without saying ‘when you make hear Qur’an’ it is told ‘when you make hear Adhikr’. That means when Messenger or believer makes hear Adhikr the Kuffar, they make allegation about the Messenger and believer who explains Adhikr that he is a Jinn affected man, odd liar, sorcerer, strayed one, etc. and will try to make interruption towards the propagation of Adhikr. But as explained in verses 9: 32; and 61: 8, the Lord of the universe will spread His Light-Adhikr-even if the disbelievers are how much hating it. See explanation 22: 72; 41: 26-29; and 68: 2.
