And from those who are saying as: "Indeed, we are helpers", We had taken their pledge; then they forgot a big portion of what they had been reminded, so We have stirred enmity and hate among them up to the Day of Judgment, and certainly Lord Allah will inform them with what they had been producing.
As explained in verse 3: 52 the disciples of Jesus were ready to help the Lord by conveying His Message to the entire mankind. Gradually they deviated from the covenant explained in verses 2: 26-27, and different groups were formed among them. They received the name Christians which means those who believed in Christ. It is actually against verse 22: 78 which says: "Lord has named true followers of every Messenger as Muslims". As they have deviated from the Truth, enmity and hatred developed in between them as explained in verses 4: 171-172.
Today the Arabic Quran reading Fujjar who have inherited the last version of the Lord's Book Adhikr deviate into different groups. They strayed from the true way of life more than any other people. By hiding and rejecting Adhikr, they have become the true disbelievers mentioned in 520 places in the Book. They are following satanic footsteps like sodomy, bloodshed, killing, smuggling, theft, and terrorism more than any other people all around the world. These people are united in sins and enmity rejecting the command of verse 5: 2, so these worthless people will be dragged prone on their faces into Hell as explained in verses 25: 33-34. Upon them, the wrath and curse of the Lord are affected, and Hell is kept prepared for them as their returning place as told in verse 48: 6. The Fujjar will argue, blame and curse each other in Hell as explained in verses 2: 165-167. See explanation 2: 2, 79, 213; 3: 84-85, and 4: 140.
