Narrated Muawiyah bin al-Hakam al-Sulami: I said: Messenger of Allah! among us there are men who practice divination by drawing lines. He said: There was a Prophet who drew lines, so if anyone does it as he drew lines, that is right.

Benefits and Issues:
The knowledge of lines (palmistry) was initially with a prophet, but later on, it did not continue.
So how can anyone now claim that this is exactly the same as what that prophet possessed? Rather, it is certain that it is mere conjecture and doubtful.
Therefore, it is obligatory to avoid it.
