some relevant proof or some quotes from Quran and Sunnah please ( as I can uses these hadith or from Quran and your answer to my friend if ever in the future I explain to her about my religion Islam Inshallah ). I have this friend who realy close to me and from Dr zakir naik has said say merry christmas is haraam and wrong It is even in the state if shirk. But what if it is a struggle for me to explain to this person as this friend says Eid Mubarak to me everytime it is Eid. I was just wondering if say merry Christmas but not intentionally just to make her feel happy. She reckon she would be offended if says Eid Mubarak and I don't say merry Christmas please help.
