Sayyiduna Jabir (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) laid siege to Banu Muharib at the place of Nakhl. Then it was announced among the people that the prayer was about to be established. So the Noble Prophet (peace and blessings be upon him) divided the Muslims into two groups. One group faced the enemy; they were conversing among themselves. The other group, the Noble Prophet (peace and blessings be upon him) led in two rak‘ahs and then concluded the prayer with salam. Those people got up and went to take the place of their companions. Then the second group came, and the Noble Prophet (peace and blessings be upon him) also led them in two rak‘ahs. In this way, the Noble Prophet (peace and blessings be upon him) performed four rak‘ahs, and each group performed two rak‘ahs.
