al-'Ala' bin al-Hadrami · General Behavior (Kitab Al-Adab)

Make intercession, you will be rewarded, for I purposely delay a matter so that you intercede and then you are rewarded. The Messenger of Allah (ﷺ) said: If you make intercession, you will be rewarded.

A similar tradition has also been transmitted by Abu Musa from the prophet (May peace be upon him) through a different chain of narrators.
