All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
Perhaps you are referring to fatwa 339592. What we said in that fatwa is the same that we say here about wearing the Ghutrah (Saudi head cloth) in your country. The basic principle is that you are not obliged to obey your parents in this regard unless the reason they are forbidding you from wearing it is valid, such as is the case if they fear that harm may befall you and that they would accordingly be harmed. If this is the case, then it is obligatory to obey them even if they do not live with you in the same country. You should obey them and show dutifulness towards them to the best of your abilities. We believe that the matter would be easier for you if you give up wearing it for the sake of earning their pleasure.
Allah knows best.
