Once Umar (ra) got together with all the sahabah. He asked them to ask Allah for anything. One sahabah asked Allah “I wish this room was full of gold and silver and I would give it all to the cause of Allah”, another said “Oh Allah I want the mount of Uhud in gold to give away in charity”. The sahabah asked Umar (ra) what was his dua. Umar (ra) replied ” I wish this room was full of men like the sahabah of the Prophet (pbuh). So I could spread Islam to this dunya”.
