Hazrat Abu Zar (radhiyallahu ‘anhu) remained in Shaam until the era of Hazrat Uthmaan (radhiyallahu ‘anhu). During the rule of Hazrat Uthmaan (radhiyallahu ‘anhu), Hazrat Mu‘aawiyah (radhiyallahu ‘anhu), the governor over Shaam, wrote to Hazrat Uthmaan (radhiyallahu ‘anhu) and mentioned that the people were complaining about Hazrat Abu Zar (radhiyallahu ‘anhu) on account of the great degree of abstinence of the dunya which he possessed. Hazrat Abu Zar (radhiyallahu ‘anhu) had a natural aversion for wealth and would insist that those people who possessed extra wealth should give their extra wealth away in sadaqah. Hazrat Uthmaan (radhiyallahu ‘anhu) therefore summoned him from Shaam and asked him to stay in Rabzah. Rabzah is a place approximately three day’s journey from Madinah Munawwarah.

The Prophecy of Rasulullah (sallallahu ‘alaihi wasallam) regarding Hazrat Abu Zar (radhiyallahu ‘anhu) leaving Shaam:
Hazrat Abu Zar (radhiyallahu ‘anhu) narrates the following:
Rasulullah (sallallahu ‘alaihi wasallam) was once reciting the following Aayah of the Qur’aan Majeed:
وَمَن يَتَّقِ اللَّـهَ يَجعَل لَهُ مَخرَجًا﴿٢﴾ وَيَرزُقهُ مِن حَيثُ لا يَحتَسِبُ وَمَن يَتَوَكَّل عَلَى اللَّـهِ فَهُوَ حَسبُهُ
And for those who fear Allah, He (always) prepares a way out (for him from his difficulty), and He provides for him from (sources) he could never imagine. And if anyone puts his trust in Allah then He is sufficient for him.
Rasulullah (sallallahu ‘alaihi wasallam) began to repeat this verse to me and continued to repeat it to me for some while until I began to feel drowsy. Rasulullah (sallallahu ‘alaihi wasallam) thereafter said to me, “O Abu Zar (radhiyallahu ‘anhu)! What will you do when you are taken out of Madinah Munawwarah?” I replied, “I will leave happily and pleasantly (without causing any problems) and will proceed to live in the Haram of Makkah Mukarramah like one of its pigeons.” Rasulullah (sallallahu ‘alaihi wasallam) thereafter asked, “What will you then do when you are taken out of Makkah Mukarramah?” I replied, “I will leave happily and pleasantly (without causing any problems) and proceed to Shaam, the blessed land.” Rasulullah (sallallahu ‘alaihi wasallam) again asked, “What will you then do when you are taken out of Shaam?” I replied, “In that case, by the oath of that Being who deputed you with the truth, I will place my sword on my shoulder (i.e. I will fight with those who are taking me out)!” Rasulullah (sallallahu ‘alaihi wasallam) then said, “Better than that is for you to listen and obey, even if it be an Abyssinian slave who is ruling over you.”
