Is it true that in Hell there is a valley called Habhab in which only those who caused sorrow, misery, and wretchedness to people are punished?

It is not permissible to discuss matters of the unseen except with what is stated in the Qur'an and authentic Sunnah. No authentic hadith from the Prophet (peace be upon him) mentions the valleys of Hell, their names, or their number. The narrations that mention the valleys of Hell, such as "Habhab," "Jabb al-Ḥuzn," and "al-Wayl," are weak.
