They will say ‘there were three, the fourth of was their dog’; and they will say ‘there were five, the sixth of them was their dog’, that all are guessing at the unseen; and they will say ‘there were seven, and the eighth was their dog’. You say: "My Lord is most knowing of their number”. None knows them except a few. So you don’t argue about them except with an obvious argument, and you don’t inquire to any among those people about them".
It is told in verse 16: 64: “Lord has not sent down Adhikr upon the Messenger except to explain the mankind about what they are differing about It, and as a Guidance and Mercy for the believing people”. So the 1 in 1000 believer who testifies Adhikr which explains everything will not have any doubt in any matter as explained in verse 16: 89. The Arabic Quran reading Fujjar who hide and reject Adhikr are having doubts about all matters. In the Hereafter, these Mujirims bend their heads near their Lord and will say: “Oh our Lord! We have seen the scene of the Hell and we have heard the sound of it, so you return us, we may do righteous deeds, indeed we have become the confirmed believers” as told in verse 32: 12. See explanation 3: 7-10; 4: 150-151 and 16: 43.
