need a refutation

[H.]

i need a refutation of this video: <removed>

where he shows that prophet muhammad saws stole fasting for ashura from the jews and that the quran promises for the sabians heaven while they were pagans and that he stole ramadan from the sabeans and prayer from the sabeans. he shows from ibn kathir that sabians worship angels, why then would they go to heaven? he goes in depth on more topics, and i have been having doubts because of this video so could someone please send a refutation

jazakallah khair

First of all, you should start your posts with Islamic greeting.  And no infidel links.  Give the title of the video only.

Thank you,
