(137) باب فِي الاِسْتِئْذَانِ
Anas b. malik said :
A man peeped into some of the apartment of the prophet (May peace be upon him). The prophet (May peace be upon him) got up taking an arrowhead or arrowheads. He said: I can still picture myself looking at the Messenger of Allah (May peace be upon him) when he was exploring to pierce him.
