Hazrat Abu Hurairah (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “No person’s wealth benefited me as much as the wealth of Hazrat Abu Bakr (radhiyallahu ‘anhu).”
Hearing this, Hazrat Abu Bakr (radhiyallahu ‘anhu) began to weep and said, “My wealth and I all belong to you, O Rasul of Allah (sallallahu ‘alaihi wasallam)!” Sunan Tirmidhi #3661 & Sunan Ibnu Maajah #94)
In the narration of Hazrat Abu Hurairah (radhiyallahu ‘anhu) in Musnad Ahmed, Rasulullah (sallallahu ‘alaihi wasallam) mentioned, “No wealth (of any person) benefited me as much as the wealth of Hazrat Abu Bakr (radhiyallahu ‘anhu).”
Hearing this, Hazrat Abu Bakr (radhiyallahu ‘anhu) began to weep, and then exclaimed thrice, “O Rasulullah (sallallahu ‘alaihi wasallam)! In reality, it was through you that Allah Ta‘ala had blessed me with everything!” (Musnad Ahmad #8790)
