TIRMIDHI 391a:
from ʿAbdullāh Ibn Buḥaynah al-Asadī Ḥalīf Banī ʿAbd al-Muṭṭalib —
"The Prophet (S) stood for the Zuhr prayer, and he had a sitting to perform, so when he completed his Salat, he performed two prostrations, saying the Takbir for each prostration. So he was sitting before saying the Salam, and the people prostrated with him in place of the sitting he forgot."
الترمذي ٣٩١a:
عن عبد الله ابن بحينه الاسدي حليف بني عبد المطلب —
أَنَّ النَّبِيَّ ﷺ قَامَ فِي صَلاَةِ الظُّهْرِ وَعَلَيْهِ جُلُوسٌ فَلَمَّا أَتَمَّ صَلاَتَهُ سَجَدَ سَجْدَتَيْنِ يُكَبِّرُ فِي كُلِّ سَجْدَةٍ وَهُوَ جَالِسٌ قَبْلَ أَنْ يُسَلِّمَ وَسَجَدَهُمَا النَّاسُ مَعَهُ مَكَانَ مَا نَسِيَ مِنَ الْجُلُوسِ قَالَ وَفِي الْبَابِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ
