Mishkat al-Masabih #1905

Abu ‘Atiya said: Masruq and I visited ‘A'isha and said, “Mother of the faithful, there are two of Muhammad’s companions one of whom hastens to break the fast and hastens to pray while the other delays breaking the fast and delays praying. She asked which of them hastened to break the fast and hastened to pray, and when we told her that he was ‘Abdallah b. Mas'ud she said, "Thus did God’s messenger do." The other was Abu Musa. Muslim transmitted it.
