Hazrat Abu Dahqana narrates that it was said to Hazrat Umar bin Khattab: Indeed, there is a boy from the people of Hira here. No one has been seen with a stronger memory or a better scribe than him. If you agree, you may appoint him as your scribe for your affairs. Whenever you need him, he will come to you. Hazrat Umar replied: In that case, I would be making someone other than the believers my companion.
