" أُمِرْتُ أَنْ أَسْجُدَ عَلَى سَبْعَةٍ - لاَ أَكُفَّ الشَّعْرَ وَلاَ الثِّيَابَ - الْجَبْهَةِ وَالأَنْفِ وَالْيَدَيْنِ وَالرُّكْبَتَيْنِ وَالْقَدَمَيْنِ "
It was narrated from Ibn 'Abbas that : 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."
