عَنْ يُوسُفَ بْنِ عَبْدِ اللَّهِ بْنِ سَلَّامٍ أَنَّهُ قَالَ سُئِلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَحْنُ خَيْرٌ أَمْ مَنْ بَعْدَنَا فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”لَوْ أَنْفَقَ أَحَدُهُمْ أُحُدًا ذَهَبًا مَا بَلَغَ مُدَّ أَحَدِكُمْ وَلَا نَصِيفَهُ“
It is narrated from Sayyiduna Yusuf bin Abdullah bin Salam (may Allah be pleased with him) that it was asked from the Messenger of Allah (peace and blessings be upon him): Are we, the Companions, superior or the people who will come after us? The Messenger of Allah (peace and blessings be upon him) said: If any man from those who come after were to spend gold equal to Mount Uhud, it would not reach even one mudd or half a mudd of what you have spent.
