Samurah bin Jundub (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Do not say to one another: 'May Allah's curse be upon you,' 'May Allah's wrath be upon you,' or 'Go to Hell.'" And in another narration: "Do not even say: 'Go into the (Hell) Fire.'" Its chain is weak. Narrated by al-Tirmidhi and Abu Dawood.
