"Whenever you see a deaf man running follow him, he has seen an impending danger not just heard it."- Has anything proverbial in this sentence?
a short, well-known pithy saying, stating a general truth or piece of advice
Note the word "well-known" in that definition. I don't think this is - at least not in English. However, as prosd says, the phrasing sounds quite proverb-like.
I interpret this as meaning that one should rely on perception of reality (eyes) rather than on what people say.
Collins: a short, memorable, and often highly condensed saying embodying, esp with bold imagery, some commonplace fact or experience
Dictionary.com: a wise saying or precept; a didactic sentence
Merriam-Webster: a brief popular saying (such as “Too many cooks spoil the broth”) that gives advice about how people should live or that expresses a belief that is generally thought to be true
Oxford: a short pithy saying in general use, stating a general truth or piece of advice
Cambridge: a short statement, usually known by many people for a long time, that gives advice or expresses some common truth
Macmillan: a short well-known statement that gives practical advice about life
Many sources consider "well-known" to be essential to a proverb. Therefore, since this statement is not well-known in any English-speaking culture, it would not commonly be regarded as an American/British/etc proverb. However, if there were a culture in which the statement were in common use, it would be considered a proverb in that culture.
