The Messenger of Allah ﷺ said: "I have been commanded to prostrate on seven, and not to tuck up my hair nor my garment: the forehead, the nose, the hands, the knees and the feet." (Using translation from Nasāʾī 1096)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ أُمِرْتُ أَنْ أَسْجُدَ عَلَى سَبْعَةِ أَعْظُمٍ الْجَبْهَةِ وَأَشَارَ بِيَدِهِ إِلَى أَنْفِهِ وَالْيَدَيْنِ وَالرُّكْبَتَيْنِ وَأَطْرَافِ الْأَصَابِعِ وَلا أَكُفَّ الثِّيَابَ وَلا الشَّعَرَ
