Likewise, taking hold of a sword while it is already unsheathed is forbidden. When a person reaches out to grasp a naked blade, his hand may shake and he could sever the other man’s hand.

The same ruling applies to a knife and anything similar: never hand it to your companion with the point or edge facing him. Instead, grip the blade yourself and present the handle toward your companion so that, should anyone’s hand slip, only you are at risk and his hand is not cut.

The same etiquette governs carrying a staff while moving through a crowd. Do not carry it horizontally, for someone walking in front of you or behind you may stumble over it. Rather, hold it upright, or lean on it vertically, so that you do not injure those around you.

All of these are examples of the commendable manners a person ought to adopt in daily life so that he does not cause harm or annoyance to others. Allah alone grants success.
