حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي عُمَرَ، قَالَ: حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ، عَنْ أَبِيهِ، قَالَ: قُبِضَ رَسُولُ اللهِ ﷺ يَوْمَ الاثْنَيْنِ فَمَكَثَ ذَلِكَ الْيَوْمَ وَلَيْلَةَ الثُّلاثَاءِ، وَدُفِنَ مِنَ اللَّيْلِ، وَقَالَ سُفْيَانُ: وَقَالَ غَيْرُهُ: يُسْمَعُ صَوْتُ الْمَسَاحِي مِنْ آخِرِ اللَّيْلِ.
