Ahadith 680 and 681 are repeats. Read here.
Narrated Abu Huraira:
Once Allah's Apostle prayed two Rakat (instead of four) and finished his prayer. Dhu-l-yadain asked him whether the prayer had been reduced or whether he had forgotten. Allah's Apostle asked the people whether Dhu-l-yadain was telling the truth. The people replied in the affirmative. Then Allah's Apostle stood up, offered the remaining two Rak`aat and then finished his prayer with Taslim and then said, "Allahu Akbar." He followed it with two prostrations like ordinary prostrations or a bit longer.
Narrated Abu Huraira:
The Prophet prayed two Rakat of Zuhr prayer (instead of four) and he was told that he had prayed two Rakat only. Then he prayed two more Rakat and finished them with the Taslim followed by two prostrations.
Prophet (SAW) had forgotten during the prayer. So he prayed two Rak`aat for Dhuhr instead of four. And when was asked about it, he immediately stood up and completed the prayer. That is, he offered the remaining two rak`aat followed by sajdah sahw (two prostrations).
Wassalam.
