(Zukhuruf) 43 : 67
الْأَخِلَّاءُ يَوْمَئِذٍ بَعْضُهُمْ لِبَعْضٍ عَدُوٌّ إِلَّا الْمُتَّقِينَ
The brotherhood among some of them upon others will be in enmity on that Day except between the heedful.
It is told in verse 39: 33 that whoever receives Adhikr and testifies It, such are the heedful. Lord has taught through His Messenger that no one will become a believer until he/she loves others in the pleasure of Allah, hates others in the displeasure of Allah, gives to others in the satisfaction of Allah, and does not give to others in the dissatisfaction of Allah. Lord has also taught that no one will become a believer until his whim follows what I have brought. In short, all relationship except under the light of Adhikr will be futile in the Hereafter. See explanation 9: 71-72; 74: 49-51; and 80: 33-37.
