(22) باب مَا يَفْعَلُ مَنْ سَلَّمَ مِنْ رَكْعَتَيْنِ نَاسِيًا وَتَكَلَّمَ
It was narrated from Abu Hurairah that:
The Messenger of Allah (ﷺ) prayed Zuhr with two rak'ahs, then said the salam. They said: "Has the prayer been shortened?" So he stood up and prayed two rak'ahs, then he said the salam, then he prostrated twice. (JA)
