Hadith record

Hadith.1334 - Abd al-Rahman ibn Abi Abdullah reported from Imam Jafar ibn Muhammad Al-Sadiq (as) that He said: "The Prophet (sw) prayed with his companions during the Battle of Dhat al-Riqa'. He divided his companions into two groups: one group faced the enemy, while the other stood behind him (for prayer). He commenced the prayer with them by saying the takbir, and they all said the takbir. He recited, and they listened silently. He bowed, and they bowed. He prostrated, and they prostrated. Then the Messenger of Allah (sw) remained standing while they prayed an additional rak'ah for themselves and then exchanged positions. The first group took their place facing the enemy, and the other group came and stood behind the Messenger of Allah (sw). He then repeated the takbir, and they followed. He recited, and they listened silently. He bowed, and they bowed. He prostrated, and they prostrated. Then the Messenger of Allah (sw) sat for the tashahhud and offered the salutation (ending the prayer). Afterward, this group completed another rak'ah for themselves, and then they exchanged greetings with one another."
