Q 2: What is
the ruling on using the Gregorian calendar to deal with those who do not know the Hijri calendar e.g.
The non-Arab Muslims or non-Muslim colleagues?
It is not permissible for Muslims to use the Gregorian calendar, as it entails imitating
the Christians whose traditions include using this calendar. Muslims have to dispense with this calendar as they have their own calendar associating them with the Prophet (peace be upon him). There is nothing wrong with using both dates when necessary.May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
