Hadith 3:24
Hudhaifah (RAA) narrated that the Messenger of Allah (ﷺ) used to prohibit the announcement of anyone’s death. Related by Ahmad and At-Tirmidhi, who rendered it Hasan.
وَعَنْ حُذَيْفَةَ - رضى الله عنه - { أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم -كَانَ يَنْهَى عَنِ اَلنَّعْيِ } رَوَاهُ أَحْمَدُ, وَاَلتِّرْمِذِيُّ وَحَسَّنَهُ
