Reply #6: I certainly do not condone such a remark if made seriously, but

[KitSileya]

I can easily envision scenarios where such a remark was made innocently I'm not all that familiar with Middle Eastern history, but the teacher could have said something along the lines that the Bedouins regarded the Quran as tantamount to toilet paper until the converted to Islam, or something like that, and the student misunderstood. On the other hand, I can also believe that the teacher said it in seriousness, in a dismissive sort of way, in which case it should be punished accordingly.

Until we know more of the situation in which the remark was made, it's difficult to judge.
