Sahih al-Bukhari 6644
Narrated Anas bin Malik:
I heard the Prophet saying, "Perform the bowing and the prostration properly (with peace of mind), for, by Him in Whose Hand my soul is, I see you from behind my back when you bow and when you prostrate."
حَدَّثَنِي إِسْحَاقُ، أَخْبَرَنَا حَبَّانُ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا قَتَادَةُ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ ـ رضى الله عنه ـ أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ
" أَتِمُّوا الرُّكُوعَ وَالسُّجُودَ، فَوَالَّذِي نَفْسِي بِيَدِهِ إِنِّي لأَرَاكُمْ مِنْ بَعْدِ ظَهْرِي إِذَا مَا رَكَعْتُمْ وَإِذَا مَا سَجَدْتُمْ ".
