Muwatta Imam Malik Book of Burials, Hadith 44

Yahya related to me from Malik that Abu'r-Rijal Muhammad ibn Abd ar-Rahman heard his mother Amra bint Abd ar-Rahman say, "The Messenger of Allah ﷺ cursed both men and women who dug up," meaning those who dug up graves.

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ أَبِي الرِّجَالِ، مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أُمِّهِ، عَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ أَنَّهُ سَمِعَهَا تَقُولُ، لَعَنَ رَسُولُ اللَّهِ ﷺ الْمُخْتَفِيَ وَالْمُخْتَفِيَةَ يَعْنِي نَبَّاشَ الْقُبُورِ .
