It was narrated from Abu Hurairah that a black woman used to sweep the mosque. The Messenger of Allah (ﷺ) noticed she was missing and he asked about her after a few days. He was told that she had died. He said: “Why did you not tell me?” Then he went to her grave and offered the funeral prayer for her.

حَدَّثَنَا أَحْمَدُ بْنُ عَبْدَةَ، أَنْبَأَنَا حَمَّادُ بْنُ زَيْدٍ، حَدَّثَنَا ثَابِتٌ، عَنْ أَبِي رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ، . أَنَّ امْرَأَةً، سَوْدَاءَ كَانَتْ تَقُمُّ الْمَسْجِدَ فَفَقَدَهَا رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ فَسَأَلَ عَنْهَا بَعْدَ أَيَّامٍ فَقِيلَ لَهُ إِنَّهَا مَاتَتْ . قَالَ " فَهَلاَّ آذَنْتُمُونِي " . فَأَتَى قَبْرَهَا فَصَلَّى عَلَيْهَا .
