Jaabir bin Samurah (may Allah be pleased with him) says:
"Messenger of Allah ﷺ had a wide mouth. There were red lines in the whiteness of his eyes. He had little flesh on his heels."

حَدَّثَنَا أَبُو مُوسَى مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ سِمَاكِ بْنِ حَرْبٍ، قَالَ: سَمِعْتُ جَابِرَ بْنَ سَمُرَةَ، يَقُولُ: كَانَ رَسُولُ اللهِ ﷺ ضَلِيعَ الْفَمِ، أَشْكَلَ الْعَيْنِ، مَنْهُوسَ الْعَقِبِ.
