We haven’t heard this from any other place, indeed this is nothing except a fabricated thing.
Today, when the believer reminds the Fujjar by quoting verses that only one Party is satisfied by Allah and it is only the Lord’s party as mentioned in verse 58: 22, and while different organizations of them are Satan’s parties as mentioned in verses 58: 19, the Fujjar will also raise the argument: “He (believer) is making all our organizations into a single organization, it is a wonderful and a fabricated thing, and we have never heard this from our forefathers”. Meanwhile, these Fujjar have already read these verses in the Arabic Quran. Thus they have become the original disbelievers mentioned in verses 4: 150-151 and Mushriks as mentioned in verses 30: 30-32. The verses they saw, read, touched, and heard will argue and witness against these Fujjar and will push them into Hell. The Impartial Lord won’t send anyone to Paradise or hell. See explanation 37: 35-36.
