Statement of kufr

Assalam o alikum respected mufti. I asked a fatwa from you and u replied “you have not left the fold of Islam make a lot of taubah and astagfaar”. Still my heart is scared if i am out of Islam or not. I fear Allah and love Islam. I dont want to be out of fold of Islam. Dear mufti please read the problem again mentioned below though you already said that I have not left the fold of Islam.

I am very tensed and not 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”. My intention was that some person in this world will fuck his mother and Allah will make this happen to punish his mother. Or there was no intention at all. I am confused. But all I know is that i can NEVER say such sentence in literal meaning. 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
