Does a divorce take place if a husband types "divorced" on his mobile phone, intending divorce, then immediately retracts and types "ʿAyn", when he had no desire for divorce, knowing that the word "divorced" is not a metaphorical expression?

The aforementioned divorce does not take effect, because it only takes effect with an explicit verbal declaration or an implicit one accompanied by intention. The questioner did not write an explicit divorce, and the word "طالع" (tali') is not suitable as an implicit expression for it. One should turn away from the whispers of divorce and other matters, and be wary of indulging in them, seeking Allah's help and making abundant supplications.
