A sick person who is in the state of ihram needs to shave his head and offers the fidyah (ransom payment) before shaving his head. Is this permissible?

Question : For example, a sick person. He says he is a mushrik (one who associates partners with Allah) and needs to shave his head, so he offers the fidyah before shaving his head. Is this permissible or not?

Answer : It is permissible. Now, if he shaves his head, the fidyah becomes obligatory. That is, if he offers it and then shaves his head, the fidyah becomes obligatory. In this case, it is permissible to offer the fidyah before the obligation arises, but after the cause exists. If someone says, "I am afraid the sun will hurt me and I want to cover my head, so I want to pay the expiation now," you tell him to wait until the cause occurs. The cause? Because the cause has not yet occurred. This is an established rule: if the cause for the obligation of an act of worship exists and one performs it after the cause exists, it is valid, even if it was not yet obligatory, or even if the condition for obligation was not yet met. However, if the cause does not exist, it is not valid.
