Mishkat al-Masabih #259

Abu Huraira reported God’s messenger as saying, “Seek refuge in God from the pit of sorrow.” On being asked what the pit of sorrow was, he replied, “ It is a wadi in jahannam from which jahannam seeks refuge four hundred times every day.” When God’s messenger was asked who would enter it, he replied, “The Qur’an readers who are ostentatious in what they do.” Tirmidhi transmitted it, and Ibn Majah has the same, adding in it, “Among the Qur’an readers who are most hateful to God are those who visit princes.” Al-Muharibi said that he meant tyrants.
