Hazrat Abu Saeed Al-Khudrira narrated that the Holy Prophetsa said:
“Do not abuse my companions, for if any one of you spent gold equal to Uhud (in Allah’s Cause) it would not be equal to a mud [510g to 750g] or even a half mud spent by one of them.”
(Sahih al-Bukhari, Kitab al-Fazail Ashab al-Nabisa)
