The Messenger of Allah ﷺ said: Do you find me seeing towards the Qibla only? By Allah, your bowing and your prostrating are not hidden from my view. Verily I see them behind my back.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ هَلْ تَرَوْنَ قِبْلَتِي هَا هُنَا فَوَاللَّهِ مَا يَخْفَى عَلَىَّ رُكُوعُكُمْ وَلاَ سُجُودُكُمْ إِنِّي لأَرَاكُمْ وَرَاءَ ظَهْرِي
