Do as you are bidden and you'll never be to blame.

The proverb presents obedience to instructions as protection from blame if the result turns out badly.

It suggests that responsibility for a directed action rests with the person who gave the instruction, rather than the person who followed it.

Use it to reassure someone who is hesitant to follow instructions because they fear being blamed for the outcome. It can also express a person's defense of an action they took at someone else's direction.
