Salam alaikum, years ago we presented to respected reader saheeh shia hadith, that Quran previously contain 17000 verses.
Here scan copy of mention narration from Usool al-Kafi, printed by Darul Adwa, thk: Ali Akbar al-Ghifare
Let us see how this hadith changed when this book was printed by Darul Hadith al-Ilmiya as-Saqafiya:
Verily, the Qur’an which Gibril [as] came up with to Muhammad [saw] is 7,000 verses
So with the help of shia editors, 17000 became 7000. Easy, huh?
