(19) باب السَّهْوِ فِي الصَّلاَةِ وَالسُّجُودِ لَهُ
'Abdullah b. Malik ibn Buhaina al-Asadi reported:
The Messenger of Allah (ﷺ) stood up (at the end of two rak'ahs) when he had to sit and proceeded on with the prayer. But when he was at the end of the prayer, he performed a prostration before the salutation and then pronounced the salutation.
