question #3 Sahih al-Bukhari 3673, Book 62, Hadith 23 : Why is it important to refrain from criticizing the companions of the Prophet?

The Prophet (ﷺ) 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 or even a half Mud spent by one of them.”
