they went out with the Messenger of Allah one day and he saw a new grave. He said: "What is this?" They said: "This is so-and-so, the freed slave woman of Banu so-and-so" - whom Messenger of Allah knew - "She died at midday and we did not like to wake you up when you were fasting and taking a nap." The Messenger of Allah stood (for prayer) and the people formed rows behind him. He said four Takbirs over her then he said: "If anyone among you dies while I am still among you, inform me, for my prayer for his is a mercy."  

عَنْ عَمِّهِ يَزِيدَ بْنِ ثَابِتٍ أَنَّهُمْ خَرَجُوا مَعَ رَسُولِ اللَّهِ ﷺ ذَاتَ يَوْمٍ فَرَأَى قَبْرًا جَدِيدًا فَقَالَ مَا هَذَا قَالُوا هَذِهِ فُلاَنَةُ مَوْلاَةُ بَنِي فُلاَنٍ فَعَرَفَهَا رَسُولُ اللَّهِ ﷺ مَاتَتْ ظُهْرًا وَأَنْتَ نَائِمٌ قَائِلٌ فَلَمْ نُحِبَّ أَنْ نُوقِظَكَ بِهَا فَقَامَ رَسُولُ اللَّهِ ﷺ وَصَفَّ النَّاسَ خَلْفَهُ وَكَبَّرَ عَلَيْهَا أَرْبَعًا ثُمَّ قَالَ لاَ يَمُوتُ فِيكُمْ مَيِّتٌ مَا دُمْتُ بَيْنَ أَظْهُرِكُمْ إِلاَّ آذَنْتُمُونِي بِهِ فَإِنَّ صَلاَتِي لَهُ رَحْمَةٌ  

"Some people passed by an isolated grave with the Messenger of Allah and he led them in prayer and they formed rows behind him." I said: "Who was that O Abu 'Amr?" He said: "Ibn 'Abbas."  

أَخْبَرَنِي مَنْ مَرَّ مَعَ رَسُولِ اللَّهِ ﷺ عَلَى قَبْرٍ مُنْتَبِذٍ فَأَمَّهُمْ وَصَفَّ خَلْفَهُ قُلْتُ مَنْ هُوَ يَا أَبَا عَمْرٍو قَالَ ابْنُ عَبَّاسٍ  

"Someone who saw the Prophet pass by an isolated grave told me that he offered the funeral prayer there and his Companions formed rows behind him." It was said: "Who told you this?" He said: "Ibn 'Abbas."  

أَخْبَرَنِي مَنْ رَأَى النَّبِيَّ ﷺ مَرَّ بِقَبْرٍ مُنْتَبِذٍ فَصَلَّى عَلَيْهِ وَصَفَّ أَصْحَابَهُ خَلْفَهُ قِيلَ مَنْ حَدَّثَكَ قَالَ ابْنُ عَبَّاسٍ  

That the Prophet prayed at the grave of a woman after she had been buried.  

أَنَّ النَّبِيَّ ﷺ صَلَّى عَلَى قَبْرِ امْرَأَةٍ بَعْدَ مَا دُفِنَتْ
