The World Federation One Stop Fiqh

Ruling 11

If someone relates a mujtahid’s fatwa to a second person, in the event that the mujtahid’s fatwa changes, it is not necessary for him to inform that second person that the fatwa of the mujtahid has changed. However, if after relating a fatwa a person realises that he has made a mistake and his statement will cause that second person to act against his legal duty, he must, based on obligatory precaution, rectify his mistake if possible.
