Muwatta Malik #564
Burials
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي بَكْرِ بْنِ عُثْمَانَ بْنِ سَهْلِ بْنِ حُنَيْفٍ، أَنَّهُ سَمِعَ أَبَا أُمَامَةَ بْنَ سَهْلِ بْنِ حُنَيْفٍ، يَقُولُ كُنَّا نَشْهَدُ الْجَنَائِزَ فَمَا يَجْلِسُ آخِرُ النَّاسِ حَتَّى يُؤْذَنُوا .
Yahya related to me from Malik from Abu Bakr ibn Uthman ibn Sahl
ibn Hunayf that he had heard Abu Umama ibn Sahl ibn Hunayf say, "We
used to attend funeral processions, and the last of the people would
not sit until they had been given permission ."
