Everyone loves a catchy phrase, especially one that sends us off to the Asian tiger, China. Considering that there isn't really any knowledge to get for English-speaking folks, either Islamic or secular in nature, perhaps China isn't the greatest destination? (Excuse the tongue-in-cheek comment)
If there is one so-claimed hadith (Prophetic saying) that has gotten extensive coinage, I have to say it is this one. And though the message of seeking knowledge is consistent with the Prophetic teachings, unfortunately this hadith is likely not Prophetic. It is also somewhat amusing that some of the leading opponents of hadith still love to quote this one… I would call this an ironic form of poetic justice, because it really says a lot about how much these opponents actually know about the sciences of hadith!
