Musannaf Ibn Abi Shayba 3:4287

Hafs narrated to us, from ‘Asim, from Bakr bin ‘Abdullah al-Muzani, who said: Ibn ‘Abbas was asked about three people who prayed ‘Asr, then passed by a mosque. One of them entered and prayed, one went on his way, and one sat at the door. Ibn ‘Abbas said: "As for the one who prayed, he added good to good. As for the one who went on his way, he went for his need. And as for the one who sat at the door, he is the lowest of them."
