Punishment of Reviling Parents
“Reviling parents is of great sins” (Bukhari, Muslim, Abu Dawuud, Tirmidhi)
"May Allah curse he who reviles his father; may Allah curse he who reviles his mother.” (Imam Ahmad, Nasai)
It was also narrated that the Messenger of Allah (pbuh) said,
"In the night of Isra' (Night Journey) I saw groups of people in the Hell-Fire hanged on trunks of fire. I
asked, "Who are they, Gabriel?" He said, "They are those who revile their parents in this world.” (Major Sins, Hafiz Dhahabi)
