When a chapter is revealed, some of them say, "Whose acknowledgement has this increased?" For those who acknowledge, it increased their acknowledgment, and they rejoice.
Translation endnotes
[9:124] The language of this and following verses that repeatedly use the word "increase" and the key words, "chapter" and "acknowledgment" is prophetic since it depicts a conspiracy of hypocrites after the revelation of the Quran who attempted to add two verses to the end of this chapter. For the example of a chapter that has increased the faith of those who acknowledge and tested the hypocrites, see Chapter 74.
