Even the Old Gray Lady, the New York Times itself, is not immune to the lack of sharp-eyed copy editors.
In its opinion section today, we find an article by Efraim Karsh headlined "Muslims Won't Play Together," about the Arab boycott of the Islamic Solidarity Games scheduled to take place in April in Iran.
About a third of the way through the article, we find these two sentences:
It took a mere 24 years after the Prophet’s death for the head of the universal Islamic community, the caliph Uthman, to be murdered by political rivals. This opened the floodgates to incessant infighting within the House of Islam, which has never ceased.Doesn't it go without saying that "incessant infighting" will be something that has "never ceased"?
