Can anyone find this proverb's original Farsi?

I recently found the proverb "A blind man who sees is better than a sighted man who is blind.", and I quite liked it. Any English site I find it on states that it's of Iranian origin, but I'm unable to find the original Farsi wording; and I wouldn't trust Google Translate. If anyone is able to find the original, I would very much appreciate it.

برای همه چیز خیلی ممنون.
