Remember, when Lord Allah showed them to you as few in your sleep; and if He had shown them to you as many, you would have lost courage and would have disputed in the matter; but indeed, Allah saved you from that, Indeed, He is Knower of the state of chests.
The Lord showed to Messenger this in his sleep while they were going to Bad’r. As explained through verse 4: 118, only 1 in 1000 will become a believer. So, during every period, 1 in 1000 believer must do Jihad against 999 disbelievers. During Messenger Muhammed’s time, Adhikr was not codified. So, the followers of Messenger if obeyed the Lord and His Messenger, they were considered as believers as told in verse 49: 14. But today since Adhikr is codified as the Splendid Book, whoever holdfasts It, he holdfasts Allah and is guided into the Straightpath as explained in verses 3: 101-103 and 5: 48.
The hypocrites and their blind followers by rejecting Adhikr—the Unbreakable Rope explained in verse 2: 256—are welcoming the Satan Antichrist. They would not become believers, nor shall their belief be benefited while Antichrist appears (1 of the 10 crucial signs of Doomsday) as explained in verse 6: 158. By the second coming of Jesus, Antichrist will be killed and all other people belonging to Messenger’s community will approve Jesus and Islam. They will kill the hypocrites and their blind followers as explained in verses 9: 5, 123 and 4: 91. See explanations 3: 13; 4: 158-159 and 5: 56.
