Musannaf Ibn Abi Shaybah 6828 — Repeating the prayer

Bakr bin Abdullah al-Muzani said: Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) was asked about three men who prayed Asr and then passed by a mosque: one man prayed with them, the second went on, and the third sat down by the door of the mosque. What is the ruling on these three? He said: "The one who prayed with them gained good upon good; the one who went on, went for his need; and the one who sat at the door of the mosque did something worthless and lowly."
