Sunan Ibn Majah, Book 6, Hadith 1616 (In-Book) ⓘ
It was narrated that Bara’ bin ‘Azib said: “We went out with the Messenger of Allah for a funeral, and we came to a grave. He sat down and we sat down, as if there were birds on our heads.”
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو خَالِدٍ الأَحْمَرُ، عَنْ عَمْرِو بْنِ قَيْسٍ، عَنِ الْمِنْهَالِ بْنِ عَمْرٍو، عَنْ زَاذَانَ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، قَالَ خَرَجْنَا مَعَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فِي جِنَازَةٍ فَانْتَهَيْنَا إِلَى الْقَبْرِ فَجَلَسَ وَجَلَسْنَا كَأَنَّ عَلَى رُءُوسِنَا الطَّيْرَ .
