The Quran root ن ف ع n-f-ʿ

وَاتَّبَعُوا مَا تَتْلُو الشَّيَاطِينُ عَلَىٰ مُلْكِ سُلَيْمَانَ وَمَا كَفَرَ سُلَيْمَانُ وَلَٰكِنَّ الشَّيَاطِينَ كَفَرُوا يُعَلِّمُونَ النَّاسَ السِّحْرَ وَمَا أُنزِلَ عَلَى الْمَلَكَيْنِ بِبَابِلَ هَارُوتَ وَمَارُوتَ وَمَا يُعَلِّمَانِ مِنْ أَحَدٍ حَتَّىٰ يَقُولَا إِنَّمَا نَحْنُ فِتْنَةٌ فَلَا تَكْفُرْ فَيَتَعَلَّمُونَ مِنْهُمَا مَا يُفَرِّقُونَ بِهِ بَيْنَ الْمَرْءِ وَزَوْجِهِ وَمَا هُم بِضَارِّينَ بِهِ مِنْ أَحَدٍ إِلَّا بِإِذْنِ اللَّهِ وَيَتَعَلَّمُونَ مَا يَضُرُّهُمْ وَلَا يَنفَعُهُمْ وَلَقَدْ عَلِمُوا لَمَنِ اشْتَرَاهُ مَا لَهُ فِي الْآخِرَةِ مِنْ خَلَاقٍ وَلَبِئْسَ مَا شَرَوْا بِهِ أَنفُسَهُمْ لَوْ كَانُوا يَعْلَمُونَ ١٠٢

يَنفَعُهُمْ yanfaʿuhum · profits them

And they followed [instead] what the devils had recited during the reign of Solomon. It was not Solomon who disbelieved, but the devils disbelieved, teaching people magic and that which was revealed to the two angels at Babylon, Hārūt and Mārūt. But they [i.e., the two angels] do not teach anyone unless they say, "We are a trial, so do not disbelieve [by practicing magic]." And [yet] they learn from them that by which they cause separation between a man and his wife. But they do not harm anyone through it except by permission of Allāh. And they [i.e., people] learn what harms them and does not benefit them. But they [i.e., the Children of Israel] certainly knew that whoever purchased it [i.e., magic] would not have in the Hereafter any share. And wretched is that for which they sold themselves, if they only knew. (Surah Al-Baqarah, 2:102)

وَاتَّقُوا يَوْمًا لَّا تَجْزِي نَفْسٌ عَن نَّفْسٍ شَيْئًا وَلَا يُقْبَلُ مِنْهَا عَدْلٌ وَلَا تَنفَعُهَا شَفَاعَةٌ وَلَا هُمْ يُنصَرُونَ ١٢٣

تَنفَعُهَا tanfaʿuhā · will benefit it

And fear a Day when no soul will suffice for another soul at all, and no compensation will be accepted from it, nor will any intercession benefit it, nor will they be aided. (Surah Al-Baqarah, 2:123)

يَسْأَلُونَكَ عَنِ الْخَمْرِ وَالْمَيْسِرِ قُلْ فِيهِمَا إِثْمٌ كَبِيرٌ وَمَنَافِعُ لِلنَّاسِ وَإِثْمُهُمَا أَكْبَرُ مِن نَّفْعِهِمَا وَيَسْأَلُونَكَ مَاذَا يُنفِقُونَ قُلِ الْعَفْوَ كَذَٰلِكَ يُبَيِّنُ اللَّهُ لَكُمُ الْآيَاتِ لَعَلَّكُمْ تَتَفَكَّرُونَ ٢١٩

نَّفْعِهِمَا nafʿihimā · (the) benefit of (the) two

They ask you about wine and gambling. Say, "In them is great sin and [yet, some] benefit for people. But their sin is greater than their benefit." And they ask you what they should spend. Say, "The excess [beyond needs]." Thus Allāh makes clear to you the verses [of revelation] that you might give thought (Surah Al-Baqarah, 2:219)

وَالْأَنْعَامَ خَلَقَهَا لَكُمْ فِيهَا دِفْءٌ وَمَنَافِعُ وَمِنْهَا تَأْكُلُونَ ٥

وَمَنَافِعُ wamanāfiʿu · and benefits

And the grazing livestock He has created for you; in them is warmth and [numerous] benefits, and from them you eat. (Surah An-Nahl, 16:5)
