Narrated 'Amir:
حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ ، حَدَّثَنَا يَحْيَى بْنُ أَبِي بُكَيْرٍ ، حَدَّثَنَا زَائِدَةُ ، حَدَّثَنَا أَبُو إِسْحَاقَ الشَّيْبَانِيُّ ، عَنْ عَامِرٍ ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ أَتَى رَسُولُ اللَّهِ صلى الله عليه وسلم قَبْرًا، فَقَالُوا هَذَا دُفِنَ، أَوْ دُفِنَتِ الْبَارِحَةَ. قَالَ ابْنُ عَبَّاسٍ ـ رضى الله عنهما ـ فَصَفَّنَا خَلْفَهُ ثُمَّ صَلَّى عَلَيْهَا.
Ibn `Abbas (who was at that time a boy) said, "Allah's Messenger (ﷺ) came to a grave and the people said, 'He or she was buried yesterday.' " Ibn `Abbas added, "We aligned behind the Prophet (ﷺ) and he led the funeral prayer of the deceased."
