Is a person in ihram excused if he falls into the prohibitions of ihram while forgetting or being ignorant?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: If one commits a prohibition among the prohibitions of ihram while forgetting or being ignorant, is he excused for that absolutely?

Answer:
If one commits a prohibition among the prohibitions of ihram while forgetting or being ignorant, he is excused due to ignorance and forgetfulness. However, some of the jurists say that if the prohibition involves destruction, such as cutting his hair or killing game, he is liable for the fidyah (ransom payment). He is liable for the fidyah; the sin is dropped from him, but he is liable for the fidyah. As for if it is something that does not involve destruction, such as wearing his garment, taking an omen, or doing something that does not involve destruction, then he is excused and nothing is required of him due to forgetfulness.
