عَنْ بِلَالٍ الْعَبَسِيِّ عَنْ حُذَيْفَةَ بْنِ الْيَمَانِ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ كَانَ إِذَا مَاتَ لَهُ مَيِّتٌ قَالَ: لَا تُؤْذِنُوا بِهِ أَحَدًا، إِنِّي أَخَافُ أَنْ يَكُونَ نَعْيًا، إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَنْهَى عَنِ النَّعْيِ
When someone from among the people of Sayyiduna Hudhayfah bin Yaman (may Allah be pleased with him) passed away, he would say: Do not inform anyone of his death; I fear that this act of informing may fall under the prohibited form of announcement, and I have heard from the Messenger of Allah (peace and blessings be upon him) that he forbade announcing someone's death.
