Arabic (Original)
أَخْبَرَنَا أَبُو بَكْرِ بْنُ فُورَكٍ أنبأ عَبْدُ اللهِ بْنُ جَعْفَرٍ ثنا يُونُسُ بْنُ حَبِيبٍ ثنا أَبُو دَاوُدَ ثنا شُعْبَةُ عَنِ الْحَسَنِ بْنِ عِمْرَانَ عَنِ ابْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى عَنْ أَبِيهِ قَالَ صَلَّيْتُ خَلْفَ النَّبِيِّ ﷺ فَكَانَ لَا يُتِمُّ التَّكْبِيرَ وَهَذَا عِنْدَنَا مَحْمُولٌ عَلَى أَنَّهُ ﷺ سَهَا عَنْهُ فَلَمْ يَسْجُدْ لَهُ
English Translation
Ibn Abd al-Rahman ibn Abza narrated from his father who said: I prayed behind the Prophet (peace be upon him) and he would not complete the takbir. This, in our view, is understood to mean that he (peace be upon him) was unaware of it and did not prostrate for it.
