What is the ruling on saying "bil-haqq" (by the truth) when forgetting something? Does this count as swearing by one of Allah's Beautiful Names? What is the ruling on someone who swears by this, but does not intend Allah's Name "al-Haqq" in the oath? And what is the ruling on obsessive doubts regarding this?

The people of Egypt are known for saying "bil-haqq" (by the truth) or "haqqan" (truly), meaning "speak truthfully." This is not intended as an oath by God's name, and therefore, it does not take the ruling of an oath. The questioner is advised to persist in supplication and humble entreaty, to distract themselves from intrusive thoughts, and to consult a trusted psychiatrist.
