Sahih al-Bukhari 6574
Narrated 'Ata (while Abu Huraira was narrating (see previous hadith)):
Abu Sa`id was sitting in the company of Abu 
Huraira and he did not deny anything of his narration till he reached his saying: "All this and as much 
again therewith are for you." Then Abu Sa`id said, "I heard Allah's Messenger (ﷺ) saying, 'This is for you 
and ten times as much.' " Abu Huraira said, "In my memory it is 'as much again therewith.' "
قَالَ عَطَاءٌ وَأَبُو سَعِيدٍ الْخُدْرِيُّ جَالِسٌ مَعَ أَبِي هُرَيْرَةَ، لاَ يُغَيِّرُ عَلَيْهِ شَيْئًا مِنْ حَدِيثِهِ حَتَّى انْتَهَى إِلَى قَوْلِهِ ‏"‏ هَذَا لَكَ وَمِثْلُهُ مَعَهُ ‏"‏‏.‏ قَالَ أَبُو سَعِيدٍ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ هَذَا لَكَ وَعَشَرَةُ أَمْثَالِهِ ‏"‏‏.‏ قَالَ أَبُو هُرَيْرَةَ حَفِظْتُ ‏"‏ مِثْلُهُ مَعَهُ ‏"‏‏.‏
