Hazrat Abu Moosa (radhiyallahu ‘anhu) narrates the following:
I was once in the blessed company of Rasulullah (sallallahu ‘alaihi wasallam) in one of the orchards of Madinah Munawwarah when a person came and sought permission to enter the orchard. Hearing the person’s request, Rasulullah (sallallahu ‘alaihi wasallam) said to me, “Allow him to enter and give him the glad tidings of a high stage in Jannah.” I thus opened the door for the person and found him to be none other than Hazrat Abu Bakr (radhiyallahu ‘anhu). I conveyed to him the glad tidings which Rasulullah (sallallahu ‘alaihi wasallam) had mentioned, at which he praised Allah Ta‘ala in gratitude.
Soon thereafter, another person came and requested to enter the orchard. Hearing his request, Rasulullah (sallallahu ‘alaihi wasallam) said to me, “Allow him to enter and give him the glad tidings of a high stage in Jannah.” I thus opened the door for the person, and found that he was none other than Hazrat ‘Umar (radhiyallahu ‘anhu). I conveyed to him the glad tidings which Rasulullah (sallallahu ‘alaihi wasallam) had mentioned, at which he praised Allah Ta‘ala in gratitude.
After some time, another person sought permission to enter the orchard. Rasulullah (sallallahu ‘alaihi wasallam) said to me, “Allow him to enter, and give him the glad tidings of a high stage in Jannah, together with a trial that he will face.” When I opened the door, I found that the person was none other than Hazrat ‘Uthmaan (radhiyallahu ‘anhu). I informed him of what Rasulullah (sallallahu ‘alaihi wasallam) had mentioned, at which he praised Allah Ta‘ala in gratitude and then said, “From Allah alone do we seek assistance.” (Saheeh Bukhaari #3693)
