Assalam Alaikum, I been facing fitnah w/ my mom on issues of islam for example a wide known bi'dah Mawlid, I told my mom I don't celebrate birthdays nor will I celebrate the prophet ﷺ birthday but she argued instead may الله have mercy on her can you give me any advice regarding this بارك الله فيك

Ustadh AbdulAziz al-Haqqan

Do not take part in it, and stay dutiful and gentle with her. Advise her with good words at a calm time rather than arguing, make duʿā for her guidance, and do not despair. Also you may ask relatives she respects to advise her.
