Fasting ‘Ashoora’ for one who still owes days from Ramadaan

I still have days to make up for Ramadaan and I want to fast ‘Ashoora’. Is it permissible for me to fast ‘Ashoora before I have made up the fasts I owe? Can I fast ‘Ashoora’ and the eleventh of Muharram with the intention of making up the Ramadaan fasts, and will I get the reward for fasting ‘Ashoora’?

Praise be to Allaah.

Firstly:

You should not observe voluntary fasts when you still owe one or more days from Ramadaan, rather you should start with the fasts that you owe from Ramadaan, and then observe voluntary fasts.

Ruling on celebrating non-Muslim holidays and congratulating them

Can a muslim celebrate a non muslim holiday like Thanksgiving?

Praise be to Allaah.
Greeting the kuffaar on Christmas and other religious holidays of theirs is haraam, by consensus, as Ibn al-Qayyim, may Allaah have mercy on him, said in Ahkaam Ahl al-Dhimmah: "Congratulating the kuffaar on the rituals that belong only to them is haraam by consensus, as is congratulating them on their festivals and fasts by saying ‘A happy festival to you’ or ‘May you enjoy your festival,’ and so on.
