Thereafter, Rasulullah (sallallahu ‘alaihi wasallam) encouraged the Sahaabah (radhiyallahu ‘anhum) once again to equip the army for the expedition of Tabook. Hazrat ‘Uthmaan (radhiyallahu ‘anhu) again stood and said, “O Rasul of Allah (sallallahu ‘alaihi wasallam)! I undertake to contribute another two hundred camels with their complete saddlery (saddle blankets and saddles) in the path of Allah.”

Rasulullah (sallallahu ‘alaihi wasallam) then encouraged the Sahaabah (radhiyallahu ‘anhum) to contribute to the expedition for a third time. Hazrat ‘Uthmaan (radhiyallahu ‘anhu) again stood and said, “O Rasul of Allah (sallallahu ‘alaihi wasallam)! I undertake to contribute another three hundred camels with their complete saddlery (saddle blankets and saddles) in the path of Allah (thus bringing his total contribution of camels to six hundred camels).”

On that occasion, I saw Rasulullah (sallallahu ‘alaihi wasallam) descend from the mimbar while he was extremely pleased saying, “Hazrat ‘Uthmaan (radhiyallahu ‘anhu) will not have to do any other virtuous nafl deed after this deed to purchase his Jannah.”
