(Second chain of narration, Sayyiduna Mughira (may Allah be pleased with him) said:) Then we joined the people and saw that the prayer had been established and Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) was leading them in prayer and he had already performed one rak'ah. I was about to go and inform him about you (the Prophet, peace and blessings be upon him), but you (peace and blessings be upon him) forbade me. So we performed as much of the prayer as we caught, and whatever was left, we completed it afterwards. In another narration it is stated: Whatever rak'ah we caught, we performed it, and whatever rak'ah was left, we completed it (afterwards).
