Narrated Salim b. ‘Abdallah b. ‘Umar quoted his father as saying:
I went on an expedition with God’s Messenger to Najd, and when we came in front of the enemy we drew up in line facing them. God’s Messenger then stood up and led us in prayer, and one section stood up along with him while another faced the enemy. He prayed a rak'a with those who were with him and made two prostrations, and then they changed places with those who had not prayed. When they came God’s Messenger prayed a rak'a with them and made two prostrations, then he uttered the salutation and each of them got up and left, after which he prayed a rak'a alone and made two prostrations. Nafi‘ transmitted something similar, adding that when there was greater cause for fear than on that occasion they prayed standing on their feet or mounted, without considering whether or not they were facing the qibla. Nafi‘ said he thought God’s Messenger was the one on whose authority Ibn ‘Umar mentioned that.
Abu Huraira reported God’s Messenger as saying, “If anyone is in time for a rak'a of the Friday prayer he should pray another as well, but if one misses the two rak'as he should pray four.” Or he said, “The noon prayer.”
Yazid b. Ruman told on the authority of Salih b. al-Khawwat on the authority of one who prayed in time of danger along with God’s Messenger at the battle of Dhat ar-Riqa'* that a section formed a line along with him and a section faced the enemy. He led the section which was along with him in a rak'a, then remained standing while they finished the prayer by themselves. They then departed and drew up in line facing the enemy, and when the other party came he led them in the remaining rak'a of his prayer, after which he remained seated while they finished the prayer by themselves. He then led them in uttering the salutation.
* This was during an expedition against some sections of Ghatafan in 4 A.H
(Bukhari and Muslim.) Bukhari rendered it also by another line from al-Qasim from Salih b. al-Khawwat from Sahl b. Abu Hathma from the Prophet.
Jabir said that when God’s Messenger seated himself on the pulpit on a Friday he said, “Sit down.” Ibn Mas'ud heard that and sat down at the door of the mosque, and when God’s Messenger saw him he said, “Come here, ‘Abdallah b. Mas'ud.”
