Until they will see whatever they are promised with, then they will know to whom has the weakest helper and less in multitude.
‘Whatever they are promised” is death in the case of individual, where as in the case of whole mankind it is the Day of Judgement. The nine hundred and ninety nine out of each thousand Fujjar who are the inmates of Hellfire by involving in different parties of Satan are thinking that they are the big party and are capable to help one another. They are considering about the one in thousand believer who lives here depending only upon Allah as he is an odd person and there is no one to help him. But this verse warns the Fujjar that at the time of their death they will understand that their thoughts were false. At that time only these Mujirims who have taken Satan as protector will realize the fact that the party of Believer Allah which includes Allah, His Messengers, Angels and believers from mankind and Sprites are the strongest and powerful. See explanation 7: 48-49; 38: 5-62; and 40: 49-50.
