Muwatta Imam Malik Book of Burials, Hadith 29

Yahya related to me from Malik that he had heard that Umm Salama, the wife of the Prophet ﷺ used to say, "I did not believe that the Messenger of Allah ﷺ had died until I heard the pickaxes fall."

وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ أُمَّ سَلَمَةَ، زَوْجَ النَّبِيِّ ﷺ كَانَتْ تَقُولُ مَا صَدَّقْتُ بِمَوْتِ النَّبِيِّ ﷺ حَتَّى سَمِعْتُ وَقْعَ الْكَرَازِينِ .
