Is it true that whoever has the heart line meeting the head line in their hand is one of the Zuharis or a child of the jinn, and should the child be informed of this to be wary of sorcerers using them to extract treasures?

The world of the Jinn is part of the unseen, and no one has knowledge of their affairs except through sacred texts, such as the Almighty's saying: "Indeed, he sees you, he and his tribe, from where you do not see them," and His saying: "Say, 'It has been revealed to me that a group of jinn listened and said, "Indeed, we have heard an amazing Qur'an."'"

As for the distinction of palm lines where the heart line and the head line meet in a single line, and labeling their owners as "Al-Zohari" or claiming them to be offspring of the Jinn, there is no sacred evidence for this, and a Muslim should not delve into it or seek its validity.

For protection from all evil, it is recommended to seek refuge in Allah Almighty, to observe His commands and avoid His prohibitions, to regularly recite the morning, evening, sleep, and waking supplications, and to frequently remember Allah Almighty.
