Hazrat Muhammad (Sallala ho alayhe wa-alyehe wasallam) ne farmaya :
” Musalmano tum me se koi shaks apni peshani (Forehead) se uss mitti ke asar ko saaf na kare jo namaz me sajdey se lagi ho ,,, q ke jab tak namaz ke sajdey ka nishan us ke chehre or peshani per hai farishtey us ke liye Dua-e-Maghfirat karte rehtay hain.”
