Uttering Kufr in Fight

Assalam o alikum. Respected Mufti I am very tensed and bot able to do my daily activities. I did not commit sin intentionally or with a bad intention of kufr. Please reply to my question as soon as possible so that I come back to my normal state. My problem is that my husband scolded me and said angrily “i will fuck your mother” I mistakenly said “Allah will fuck your mother”. I did not intend to say this in literal meaning. My intention was that some person in this world will do that and Allah will make this happen to punish her. I just said angrily and unknowingly i uttered such bad words.
this incident haplened within just seconds. And in anger i uttered bad words which i could never utter and neither i can intend such thing.
my question is that will i be out of fold of islam? Did I commit kufr? Will I have to renew nikah. Please reply me as soon as possible I am in severe depression
