وَإِذْ قَالَ مُوسَىٰ لِقَوْمِهِۦ يَٰقَوْمِ لِمَ تُؤْذُونَنِى وَقَد تَّعْلَمُونَ أَنِّى رَسُولُ ٱللَّهِ إِلَيْكُمْ ۖ فَلَمَّا زَاغُوٓا۟ أَزَاغَ ٱللَّهُ قُلُوبَهُمْ ۚ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلْفَٰسِقِينَ
And (remember) when Moses said unto his people: O my people! Why persecute ye me, when ye well know that I am Allah's messenger unto you? So when they went astray Allah sent their hearts astray. And Allah guideth not the evil-living folk.
Surah As-Saff(61:5)
