Indeed, those who are dividing their way of life and became sects, you have nothing to do with them; indeed their case returns unto Lord Allah, then He will notify them with whatever they have been doing.
The Messenger and believer have no responsibility upon the Arabic Quran reading Fujjar who don't accept Adhikr or Dhikree as the Lord's Book. Lord has not sent down Adhikr to the Messenger except to explain mankind with what they are differing about It, and as a Guidance and Mercy for the believing people as explained in verse 16: 64. It is told in verse 39: 41: "The Lord has sent down to Messenger Adhikr with ‘Truth’ for the mankind; whoever is guided, it is for their sake, while whoever strays, then it is upon their soul, the Messenger is not a custodian upon them". The Fujjar who don't judge in their individual, family and social life with Adhikr are the disbelievers, wrongdoers, and transgressors respectively as explained in verses 5: 44, 45, and 47. The Fujjar who are the Mujirims by serving Satan will be dragged prone on their faces into the Hellfire, they are in the worst place and are the most strayed as explained in verses 25: 33-34. By differentiating into different groups, they have become the true Mushrik and disbelievers as explained in verses 4: 150-151.
The Three-Time-Knower Lord will not notify anyone what they had been doing in this world; instead, He will produce for them their Recorded Book fastened upon their necks as a Spread Illuminating Open Book and will be told: "You read your Book, today you are enough for your reckoning” as told in verses 2: 148. To put it briefly, no male or female from the people of Messenger can become a believer except with Adhikr as explained in verses 3: 102-103. The believer always Glorify Lord as: "Glory is to the One Who is enough to acquaint the offenses of His servants" as explained in verse 25: 58, and "Glory is the One Who is Acquainted Observer of His servants’ offenses" as explained in verse 17: 17. The believer holdfasts Adhikr, thus he did holdfast Lord and is guided into the Straightpath as explained in verse 5: 48. See explanation 2: 85, 113; 3: 19-20; 5: 105, and 17: 13-14.
