Mishkat al-Masabih
Anas reported God’s Messenger as saying, “Perform the bowing and the prostration properly, for I swear by God that I can see you behind me." (Bukhari and Muslim.)
عَنْ أَنَسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَقِيمُوا الرُّكُوعَ وَالسُّجُودَ فَوَاللَّهِ إِنِّي لأَرَاكُمْ من بعدِي»
