Jami` at-Tirmidhi 2287
Abu Bakrah  narrated:
"One day the Prophet (s.a.w) said:
"'Who among you had a dream?' A man said: "I did. I saw as if a scale had descended from the Heavens in which you and Abu Bakr were weighed So you outweighed Abu Bakr. Abu Bkar and 'Umar were weighed, and Abu Bakr outweighed ('Umar). 'Umar and 'Uthman were  weighed and 'Umar outweighed ('Uthman). Then the scale was raised up.' Then I saw dislike in the the face of Messenger of Allah (s.a.w)."
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا الأَنْصَارِيُّ، حَدَّثَنَا أَشْعَثُ، عَنِ الْحَسَنِ، عَنْ أَبِي بَكْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ذَاتَ يَوْمٍ ‏
"‏ مَنْ رَأَى مِنْكُمْ رُؤْيَا ‏"‏ ‏.‏ فَقَالَ رَجُلٌ أَنَا رَأَيْتُ كَأَنَّ مِيزَانًا نَزَلَ مِنَ السَّمَاءِ فَوُزِنْتَ أَنْتَ وَأَبُو بَكْرٍ فَرَجَحْتَ أَنْتَ بِأَبِي بَكْرٍ وَوُزِنَ أَبُو بَكْرٍ وَعُمَرُ فَرَجَحَ أَبُو بَكْرٍ وَوُزِنَ عُمَرُ وَعُثْمَانُ فَرَجَحَ عُمَرُ ثُمَّ رُفِعَ الْمِيزَانُ ‏.‏ فَرَأَيْنَا الْكَرَاهِيَةَ فِي وَجْهِ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
