Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن أبي الدرداء رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم : "لا يكون اللعانون شفعاء، ولا شهداء يوم القيامة" ((رواه مسلم)).
The Messenger of Allah (ﷺ) said, "Those who frequently resort to cursing (people) would neither be accepted as witnesses nor as intercessors on the Day of Resurrection."[Muslim].
