Ibn Abbas (may Allah be pleased with them both) said: "He (peace and blessings be upon him) was commanded to prostrate on seven limbs and was forbidden" - in the narration of Ibn Tawus it is: "forbidden to tuck up his hair and his clothes," and the words of Amr's narration are: 'kaffu sha'rihi wa thiyabihi' (that he should not tuck up his hair and clothes).
Sufyan says that Ibn Tawus told that Tawus used to point with his hand to the forehead and the nose, and Ibn Tawus did so to demonstrate, and said: My father used to say that the nose and the forehead are one; the remaining six are the two hands, the two knees and the two feet.
Imam al-Bayhaqi (may Allah have mercy on him) says that in Sufyan's narration the mention of the nose is Tawus's explanation, while Imam Muslim (may Allah have mercy on him) recorded the narration of Ibn Tawus in "Sahih Muslim" in abridged form, without the explanation.
