Maarif-ul-Quran (En) - An-Nisaa : 111
وَ مَنْ یَّكْسِبْ اِثْمًا فَاِنَّمَا یَكْسِبُهٗ عَلٰى نَفْسِهٖ١ؕ وَ كَانَ اللّٰهُ عَلِیْمًا حَكِیْمًا
And whoever commits a sin, commits it only against himself. And Allah is All-Knowing, All-Wise.
In the event that these people choose not to repent despite the option given to them, the seventh verse (111) carries the assurance that this action of theirs brings no harm to Almighty Allah or His Messenger or to Muslims. The sad nemesis of a person's evil deed shall be faced by the person himself.
