There isn't much out there, but this is a pretty good collection of sayings -- the best I've found so far -- which I've incorporated into my Arabic studies. I have found them reliable, because my teachers understand them when I use them. They are very practical and usable sayings, for the most part. I also found that they helped expand my vocabulary in a fun way. I'm not qualified to judge the quality of the selection or the translations, but they seem pretty accurate overall.
