لَاهِيَةً قُلُوبُهُمْ ۗ وَأَسَرُّوا۟ ٱلنَّجْوَى ٱلَّذِينَ ظَلَمُوا۟ هَلْ هَـٰذَآ إِلَّا بَشَرٌ مِّثْلُكُمْ ۖ أَفَتَأْتُونَ ٱلسِّحْرَ وَأَنتُمْ تُبْصِرُونَ
With their hearts distracted. And those who do wrong conceal their private conversation, [saying], "Is this [Prophet] except a human being like you? So would you approach magic while you are aware [of it]?"
قَالَ رَبِّى يَعْلَمُ ٱلْقَوْلَ فِى ٱلسَّمَآءِ وَٱلْأَرْضِ ۖ وَهُوَ ٱلسَّمِيعُ ٱلْعَلِيمُ
