A black man or a black woman used to sweep the mosque and he or she died. The Prophet ﷺ asked about her (or him). He was told that she (or he) had died. He said, "Why did you not inform me? Show me his grave (or her grave)." So he went to her (his) grave and offered her (his) funeral prayer."  

أَنَّ رَجُلاً أَسْوَدَ أَوِ امْرَأَةً سَوْدَاءَ كَانَ يَقُمُّ الْمَسْجِدَ فَمَاتَ فَسَأَلَ النَّبِيُّ ﷺ عَنْهُ فَقَالُوا مَاتَ قَالَ أَفَلاَ كُنْتُمْ آذَنْتُمُونِي بِهِ دُلُّونِي عَلَى قَبْرِهِ أَوْ قَالَ قَبْرِهَا فَأَتَى قَبْرَهُ فَصَلَّى عَلَيْهِ  

A black person, a male or a female used to clean the Mosque and then died. The Prophet ﷺ did not know about it . One day the Prophet ﷺ remembered him and said, "What happened to that person?" The people replied, "O Messenger of Allah ﷺ! He died." He said, "Why did you not inform me?" They said, "His story was so and so (i.e. regarded him as insignificant)." He said, "Show me his grave." He then went to his grave and offered the funeral prayer.  

أَنَّ أَسْوَدَ رَجُلاً أَوِ امْرَأَةً كَانَ يَقُمُّ الْمَسْجِدَ فَمَاتَ وَلَمْ يَعْلَمِ النَّبِيُّ ﷺ بِمَوْتِهِ فَذَكَرَهُ ذَاتَ يَوْمٍ فَقَالَ مَا فَعَلَ ذَلِكَ الإِنْسَانُ قَالُوا مَاتَ يَا رَسُولَ اللَّهِ قَالَ أَفَلاَ آذَنْتُمُونِي فَقَالُوا إِنَّهُ كَانَ كَذَا وَكَذَا قِصَّتَهُ قَالَ فَحَقَرُوا شَأْنَهُ قَالَ فَدُلُّونِي عَلَى قَبْرِهِ فَأَتَى قَبْرَهُ فَصَلَّى عَلَيْهِ  

Lead me to her (or his) grave. They led him to that place and he said prayer over her (or him) and then remarked: Verily, these graves are full of darkness for their dwellers. Verily, the Mighty and Glorious Allah illuminates them for their occupants by reason of my prayer over them.  

أَنَّ امْرَأَةً سَوْدَاءَ كَانَتْ تَقُمُّ الْمَسْجِدَ أَوْ شَابًّا فَفَقَدَهَا رَسُولُ اللَّهِ ﷺ فَسَأَلَ عَنْهَا أَوْ عَنْهُ فَقَالُوا مَاتَ قَالَ أَفَلاَ كُنْتُمْ آذَنْتُمُونِي قَالَ فَكَأَنَّهُمْ صَغَّرُوا أَمْرَهَا أَوْ أَمْرَهُ فَقَالَ دُلُّونِي عَلَى قَبْرِهِ فَدَلُّوهُ فَصَلَّى عَلَيْهَا ثُمَّ قَالَ إِنَّ هَذِهِ الْقُبُورَ مَمْلُوءَةٌ ظُلْمَةً عَلَى أَهْلِهَا وَإِنَّ اللَّهَ ﷻ يُنَوِّرُهَا لَهُمْ بِصَلاَتِي عَلَيْهِمْ  

A negress (or a youth) used to sweep the mosque. The Prophet ﷺ missed him, and when he asked about him the people told him that he had died. He said: Why have you not informed me ? He said: Lead me to his grave. So they led him and he prayed over him.  

أَنَّ امْرَأَةً سَوْدَاءَ أَوْ رَجُلاً كَانَ يَقُمُّ الْمَسْجِدَ فَفَقَدَهُ النَّبِيُّ ﷺ فَسَأَلَ عَنْهُ فَقِيلَ مَاتَ فَقَالَ أَلاَّ آذَنْتُمُونِي بِهِ قَالَ دُلُّونِي عَلَى قَبْرِهِ فَدَلُّوهُ فَصَلَّى عَلَيْهِ  

“Why did you not tell me?” Then he went to her grave and offered the funeral prayer for her.  

أَنَّ امْرَأَةً سَوْدَاءَ كَانَتْ تَقُمُّ الْمَسْجِدَ فَفَقَدَهَا رَسُولُ اللَّهِ ﷺ فَسَأَلَ عَنْهَا بَعْدَ أَيَّامٍ فَقِيلَ لَهُ إِنَّهَا مَاتَتْ قَالَ فَهَلاَّ آذَنْتُمُونِي فَأَتَى قَبْرَهَا فَصَلَّى عَلَيْهَا  

[Machine] A black woman used to attend the mosque regularly, but when she died, the Prophet (PBUH) missed her. He asked about her after a few days and was informed that she had died. He said, "Why didn't you inform me?" He then went to her grave and prayed for her. Ibn Abda added in his narration that Hammad informed him that Thabit said, "The Messenger of Allah (PBUH) said, 'These graves are filled with darkness for their inhabitants, but Allah illuminates them with my prayers upon them.'"  

أَنَّ امْرَأَةً سَوْدَاءَ كَانَتْ تَقُمُّ الْمَسْجِدَ فَمَاتَتْ فَفَقَدَهَا النَّبِيُّ ﷺ فَسَأَلَ عَنْهَا بَعْدَ أَيَّامٍ فَقِيلَ لَهُ إِنَّهَا مَاتَتْ فَقَالَ هَلَّا كُنْتُمْ آذَنْتُمُونِي فَأَتَى قَبْرَهَا فَصَلَّى عَلَيْهَا زَادَ ابْنُ عَبْدَةَ فِي حَدِيثِهِ قَالَ وَأَنْبَأَ حَمَّادٌ ثنا ثَابِتٌ قَالَ قَالَ رَسُولُ اللهِ ﷺ إِنَّ هَذِهِ الْقُبُورَ مَمْلُوءَةٌ ظُلْمَةً عَلَى أَهْلِهَا وَإِنَّ اللهَ ﷻ يُنَوِّرُهَا بِصَلَاتِي عَلَيْهَا
