(Mu'amin) 40 : 25
فَلَمَّا جَاءَهُمْ بِالْحَقِّ مِنْ عِنْدِنَا قَالُوا اقْتُلُوا أَبْنَاءَ الَّذِينَ آمَنُوا مَعَهُ وَاسْتَحْيُوا نِسَاءَهُمْ ۚ وَمَا كَيْدُ الْكَافِرِينَ إِلَّا فِي ضَلَالٍ

Thus when they came to them with the Truth from Us, they said: You kill sons of those who believed with him, and allow to live their woman, while the plotting of the disbelievers was nothing except astray.

As a trick to eradicate the Truth, Pharaoh, his minister Haman, and Qarun jointly decided to kill the sons of the children of Israel and allow the women of the children of Israel to live. But they couldn’t defeat the Truth. Allah caused Pharaoh, Haman, and his troops to drown in the sea. Thus, Allah teaches that all the evil plots the disbelieving hypocrites make against the Truth, Adhikr, will be futile. It is told in verses 13: 14 and 40: 50 that the prayer of disbelievers increases nothing but futility. The Arabic Quran-reading Fujjar are the real disbelievers mentioned in verses 4: 150-151. As told in verses 9: 67-68; 15: 44; 25: 33-34, 65-66; 48: 6, and 98: 6, these disbelievers will be sent to Hell as a punishment for living here aimlessly and heedlessly. See explanation 7: 127; 29: 40; 35: 43.
