(Fatwa: 891/838=L/1429)
There is no need of intention in direct Talaq, it takes place without an intention too. So, if your husband sent you SMS writing: ‘I divorce you’, then the Talaq will occur. Yes, if he wrote ‘I divorce you’ only once and did not give any other Talaq, then you were divorced by Talaq Raj’i (revocable divorce) i.e. your husband can revoke the Talaq within iddah, and after iddah he can do Nikah with you without halalah.
