أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ هَلْ تَرَوْنَ قِبْلَتِي هَا هُنَا وَاللَّهِ مَا يَخْفَى عَلَيَّ رُكُوعُكُمْ وَلَا خُشُوعُكُمْ وَإِنِّي لأَرَاكُمْ وَرَاءَ ظَهْرِي
Allah's Messenger (ﷺ) said, "You see me facing the Qibla; but, by Allah, nothing is hidden from me regarding your bowing and submissiveness and I see you from behind my back."
Bukhari 699
عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ أَقِيمُوا الرُّكُوعَ وَالسُّجُودَ فَوَاللَّهِ إِنِّي لَأَرَاكُمْ مِنْ بَعْدِي وَرُبَّمَا قَالَ مِنْ بَعْدِ ظَهْرِي إِذَا رَكَعْتُمْ وَسَجَدْتُمْ
The Prophet (ﷺ) said, "Perform the bowing and the prostrations properly. By Allah, I see you from behind me (or from behind my back) when you bow or prostrate."
