Authentic Supplication Number 225.

A man told the Messenger of Allah  that Al-Bara’ bin `Azib conveys ‘As-Salam upon him. The Prophet  said: When did you arrive? He said: Three [days] ago. He said: verily were it that you had not conveyed it, it would have been a trust upon you.

‘Al-`Adawee said it was sound, and he said that it was reported by `Abdurrazzaq, page 393 of volume 10.
