One who catches one rakah of Maghrib

Ibn al-Musayyib said: Do you know which prayer it is in which one sits after every rak'ah? It is the prayer of the man who catches one rak'ah of Maghrib; he will sit after every rak'ah.

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.

Ibrahim said: Jundub and Masruq once set out intending to pray Maghrib, and both of them caught one rak'ah of Maghrib with the imam. When the imam gave the salam, while completing the rest of his prayer Masruq sat after the second rak'ah, whereas Jundub did not sit. In the rak'ah they had caught with the imam, Jundub recited, but Masruq did not recite. What the two of them had done was mentioned before Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him), and he said: Both of you did well, but I would do what Masruq did.

Sayyiduna Sa'd (may Allah be pleased with him) said: The person who catches one rak'ah out of four with the imam should sit only after the last rak'ah, because in the prayer there are only two sittings.

Al-Hasan said: The person who catches one rak'ah of the Maghrib prayer with the imam will sit after every rak'ah.
