Does the phrase you repeated to yourself—"I divorce my wife"—count as an utterance by the tongue or a self-whisper, and does it affect the marriage contract, especially with its repetition causing psychological distress?

A divorce does not occur with the husband's utterance of "ط" (the letter "T"). A divorce only occurs with an explicit pronouncement indicating it, or with an ambiguous term (kinayah) accompanied by the intention of divorce. The questioner is advised to ease their mind, live with their wife normally, and disregard intrusive thoughts about divorce. Indeed, the divorce of one who is overcome by obsessive thoughts does not take effect, even if they explicitly utter the word of divorce. It is recommended to treat obsessive thoughts with legitimate ruqyah (definition) (Islamic incantations), maintain dhikr (remembrance of Allah) and acts of obedience, and abstain from sins.
