Is Talaaq valid if one utters it to ones relatives not ones wife in anger

AsSalamalikum Shaikh. If a person’s mother is arguing about his wife and in anger person calls his mother and says “If things are going in the same manner, I will divorce her” – “Tumlog aisa hi kartey rahonge toh main usku Talaaq de detu” Just as a warning. I uttered those statements twice once to my mother and once to my brother.
‘Does that Talaq happened’. Almost four months passed by after these incident and I prayed to Allah and asked for repetence and avoid bringing those sentences to my mouth or mind even in extreme anger and even at the previous instance the only thing I want at that was to give a warning to stop. I am at a very senior position in a company and also regular at islamic learning but at that time Iblis had taken control over me.
