According to the Wall Street Journal, Gerd-Rüdiger Puin, one of the scholars studying the manuscripts,
says the manuscripts suggested to him that the Quran "didn't just fall from heaven" but "has a history." When he said so publicly a decade ago, it stirred rage. "Please ensure that these scholars are not given further access to the documents," read one letter to the Yemen Times. "Allah, help us against our enemies."
Such unwillingness on the part of too many Muslims to risk confronting the truth, however uncomfortable it might be, brings to mind another quote, this time about Christianity:
He who begins by loving Christianity better than truth will proceed by loving his own sect of the church better than Christianity, and end in loving himself better than all. — S. T. Coleridge, Aids to Reflection, 1825
The same may be said of any religion, don't you think?
