All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
There is nothing like Allah, so anyone who describes Allah as a man or likens Him to one of the creatures then he/she refuted the Quran, and undoubtedly his/her saying is disbelief.
Allah Says (what means):
• {Nor is there to Him any equivalent.} [Quran 112:4]
• {There is nothing like unto Him, and He is the Hearing, the Seeing.} [Quran 42:11]
• {but they will never compass anything of His Knowledge.} [Quran 20:110]
• {Do you know of any similarity to Him?} [Quran 19:65]
If your friend meant Allah by his words, then he said an abominable and reprehensible statement that is considered disbelief. However, we cannot rule on a particular person that he/she is a disbeliever until after establishing clear evidence against him. Because he might mean his father or someone else, if there is an upper floor of the house in which there is a man, and he means that disagreement and raising the voice does not make him happy, then, his saying should be understood accordingly. Nonetheless, what you mentioned on your social media page and explained that likening Allah the Almighty to His Creatures is disbelief, is true and you will be rewarded for it, Allah willing.
It is worth noting that, it is necessary to beware of doubts in such matters and not give in to such thoughts or understand any sayings that have other probable meaning according to a particular incorrect meaning.
Allah knows best.
