Is it permissible for a man not to use the Hijri calendar if he fears being harmed?

The questioner : As for countries under the rule of non-Muslims or non-Ahl al-Sunnah, for example, those who are accustomed to using the Gregorian months, if this man believes that the months with Allah are the sacred months, from Dhul-Hijjah, and if he writes a letter or writes anything, meaning he writes the sacred months, he may be harmed in these circumstances, meaning they accuse him.

The Shaykh : No, I do not think so.

The questioner : Bigotry.

The Shaykh : No, no, no.

The questioner : And people do not understand it; people transgress. No, no, look.

The Shaykh : You say, for example, if you are in a place where people do not understand, say, for example, on the twelfth day of Jumada al-Thani, the year corresponding to such and such, corresponding to such and such.
