Musannaf Ibn Abi Shaybah 8709 — One who catches one rakah of Maghrib

Ibrahim said: Masruq and Jundub caught one rak'ah of Maghrib. When the imam gave the salam, Masruq stood up, prayed one rak'ah and sat down, while Jundub prayed two rak'ahs and then sat. This was mentioned to Sayyiduna Abdullah (bin Mas'ud) (may Allah be pleased with him), and he said: Both of them did well, but Masruq's action is more beloved to me, and I would do the same.
