(1) باب فِي كَسْبِ الْمُعَلِّمِ
A similar tradition has also been transmitted by 'Ubadah b. al-Samit through a different chain of narrators, but the former tradition is more perfect. This version has:
I said: What do you think about it, Messenger of Allah? He said: A live coal between your shoulders which you have put around your neck or hanged it.
