It was narrated that Bilal bin Yahya said:
“If one of the members of his family died, Hudhaifah would say: ‘Do not inform anyone of it, for I am afraid that that would be a public death announcement. I heard the Messenger of Allah ﷺ with these two ears of mine forbidding making public death announcements.’”

حَدَّثَنَا عَمْرُو بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، عَنْ حَبِيبِ بْنِ سُلَيْمٍ، عَنْ بِلاَلِ بْنِ يَحْيَى، قَالَ كَانَ حُذَيْفَةُ إِذَا مَاتَ لَهُ الْمَيِّتُ قَالَ لاَ تُؤْذِنُوا بِهِ أَحَدًا إِنِّي أَخَافُ أَنْ يَكُونَ نَعْيًا إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ـ ﷺ ـ بِأُذُنَىَّ هَاتَيْنِ يَنْهَى عَنِ النَّعْىِ .
