He issued three Talaqs without realizing

my husband and i had an argument the other night and during that argument alot of hurtful things were said to each other and the argument got out of control, and he said the three talaaqs unknowingly without thinking of the consequences. within minutes he realised what he had done, he did not mean it at all, it was said in a rage of anger and purely in an angry state. and he repented against it straight away and did taubah. however we were both in the nafaak state so i just want to know if the talaaq is valid and what do we do now. thank you.
