Kufr

Assalamualikum! I am away from my house for past two months due to my brother serious medical condition. My husband was showing me my house over video call and i said to him in urdu it does not seem like my house. Upon which he replies ( Indeed everything belongs to Allah and will return back to him ) jokingly( this sentence people says when someone dies ). I immediately said in Urdu ( kya fazool baat kar rahay ho ) meaning why are you talking rubbish? Immediately after that i realized what did i say? God forbid I did not say rubbish to that sentence which my husband said, i mean by rubbish that he used this term at inappropriate time. My intention was not kufr neither I was insulting my Religion. I am so worried about my Imaan. Please guide me what should i do in this case?
