CHAPTER: The Limbs Upon Which One Should Prostrate.
Narrated Abdullah ibn Abbas: Ibn Abbas reported the Prophet صلی اللہ علیہ وسلم as saying: I have been commanded - according to the version of Hammad: Your Prophet صلی اللہ علیہ وسلم was commanded - to prostrate on seven (bones), and not to fold back the hair or the clothing.
Ibn Abbas reported the prophet صلی اللہ علیہ وسلم as saying: I have been commanded, and sometimes the narrator said: Your prophet صلی اللہ علیہ وسلم was commanded to prostrate on seven limbs.
Abbas bin Abd al-Muttalib said that he heard the Messenger of Allah صلی اللہ علیہ وسلم as saying: when a servant (of Allah) prostrates himself, the seven limbs, i. e, his face, his palms, his knees and his feet prostrate along with him.
Narrated Abdullah ibn Umar: The Prophet صلی اللہ علیہ وسلم said: Both hands prostrate as the face prostrates. When one of you puts his face (on the ground) he should put his hands too (on the ground). And when he raises it, he should raise them too.
