Will anything be binding upon me for using scented powder to alleviate chafing of the thighs before the first stage of exiting ihram during Hajj, knowing that it is scented, but it was difficult for me to replace it due to the severe pain?

If a pilgrim (muhrim) needs to commit a prohibited act, he may do so, and he must offer a fidyah (expiatory sacrifice). The fidyah is a choice between: fasting for three days, or feeding six poor people (each receiving half a sa' [of food]), or sacrificing a sheep.
