Occasionally, on my Livejournal I’ve quoted from the Reverend Hughes’ Dictionary of Islam (1896) before. (tl;dr : informative but bigoted). This one got me to thinking:
LUNATIC. The Arabic majnun includes all mad persons, whether born idiots, or persons who have become insane. According to Muhammadan law, a lunatic is not liable to punishment for robbery, or to retaliation for murder. Zakat (legal alms) is not to be taken from him, nor is he to be slain in war. The apostasy of a lunatic does not amount to a change of faith, as in all matters, both civil and religious, he is not to be held responsible to either God or man.
So what happens to mad scientists?
