وَعَنْ اِبْنِ عَبَّاسٍ رَضِيَ اَللَّهُ عَنْهُمَا
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ («أُمِرْتُ أَنْ أَسْجُدَ عَلَى سَبْعَةِ أَعْظُمٍ: عَلَى اَلْجَبْهَةِ) وَأَشَارَ بِيَدِهِ إِلَى أَنْفِهِ وَالْيَدَيْنِ، وَالرُّكْبَتَيْنِ، وَأَطْرَافِ اَلْقَدَمَيْنِ» مُتَّفَقٌ عَلَيْهِ. 11 صحيح
The Messenger of Allah (sallallahu alayhi wa sallam) said: “I have been commanded to prostrate on seven bones; on the forehead – and he pointed at his nose, the hands (the palms), the knees and the tips (toes) of the feet.”.
