There is nothing wrong with saying of someone who defeats another “he knocked him off his throne”
Question

                I think i may have commited shirk. I said a phrase "you have knocked so and so off the throne" in regards to someone beating someone elses high score. I didnt mean anything other than perhaps they are better at the game. After reading about the throne of Allah swt. I thought this may be shirk. I am feeling extremely guilty. Please inform as to whether this is shirk and how i can repent for this.
Praise be to Allah.
	There is nothing wrong with your saying “You have knocked 
	so-and-so off the throne” to refer to someone defeating someone else in a 
	game. Thrones may be attributed to created beings in either a literal or 
	figurative sense. Kings have thrones, and it may be said that a king 
	ascended the throne, or gave up his throne. Allah, may He be exalted, says 
	concerning Yoosuf (peace be upon him) (interpretation of the meaning):

	“And he raised his parents to 
	the throne and they fell down before him prostrate. And he said: ‘O my 
	father! This is the interpretation of my dream aforetime! My Lord has made 
	it come true’”

	[Yoosuf 12:100].

	And He says concerning Balqees (interpretation of the 
	meaning):
“I found a 
	woman ruling over them", she has been given all things that could be 
	possessed by any ruler of the earth, and she has a great throne”
[an-Naml 
	27:23].

	And it may be said (in Arabic) that a person “ascended the 
	throne of the game” which is a metaphorical expression, meaning that he is 
	the winner, and if he is defeated, it is said that So-and-so knocked him off 
	his throne or caused him to fall from the throne. There is nothing wrong 
	with that, and it has no connection to the Throne of the Most Merciful, may 
	He be blessed and exalted, which is the highest and most sublime of created 
	things, and is the roof of the created universe.

	Allah, may He be exalted, has described His Throne as being 
	mighty or supreme, as He says (interpretation of the meaning):
“Allâh, Lâ 
	ilâha illa Huwa (none has the right to be worshipped but He), the Lord of 
	the Supreme Throne”
[an-Naml 
	27:26].

	We advise you to beware of waswasah (whispers from the 
	Shaytaan) regarding this and other matters, for it is a grave disease and a 
	great evil. The best remedy for that is to pay no attention to it, whilst 
	remembering Allah, may He be exalted, a great deal and turning to Him.

	And Allah knows best.
