﴿ لَاهِيَةًۭ قُلُوبُهُمْ ۗ وَأَسَرُّوا۟ ٱلنَّجْوَى ٱلَّذِينَ ظَلَمُوا۟ هَلْ هَٰذَآ إِلَّا بَشَرٌۭ مِّثْلُكُمْ ۖ أَفَتَأْتُونَ ٱلسِّحْرَ وَأَنتُمْ تُبْصِرُونَ ﴾

“their hearts set on passing ­delights; yet they who are [thus] bent on wrongdoing conceal their innermost thoughts [when they say to one another], “Is this [Muhammad] anything but a mortal like yourselves? Will you, then, yield to [his] spellbinding eloquence with your eyes open?””
