From: Bambara, West Africa
Source: Bambara (Bamanankan, Mali) oral-tradition proverb, widely and consistently attributed to Bambara across several proverb collections (e.g. bellaonline.com, inspirationalstories.com, quoterich.com), though no single primary source page could be confirmed to contain it. Earlier recorded here as documented on ankataa.com and consistent with Kassim Kone, "More than a thousand Mande Proverbs" (1995) and Charles Bailleul, "Sagesse bambara" (2005); ankataa.com's actual Bambara-proverbs post, fetched directly, does not contain it, and neither does africanmanners.wordpress.com's 25 Bambara proverbs.
