知乎，让每一次点击都充满意义 —— 欢迎来到知乎，发现问题背后的世界。 An Arabic version is ما جادلت عالما إلا وغلبته وما جادلت جاهلا إلا وغلبني ~ which if I understand well, means something like: I haven't debated with a scholar except that i defeated him, and I haven't debated with an ignorant except that he beat me. https://youtu.be/T0zWXvhEQwo?si=wNc6ihu97ShtIl7u
