Simak b. Harb quoted the authority of Jabir b. Samura for the statement that God's messenger had a dali mouth, ashkal eyes and manhush ankles. Simak was asked the meaning of a dali mouth and said it meant a large mouth. He was asked the meaning of ashkal eyes and said they were oval[*]. He was asked the meaning of manhush ankles and said there was little flesh on the ankle. *Ashkal normally means `reddish white,' here referring to redness in the white of the eye. Cf. Mirqat, 5:380. Muslim transmitted it.
وَعَنْ سِمَاكِ بْنِ حَرْبٍ عَنْ جَابِرِ بْنِ سَمُرَةَ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ضَلِيعَ الْفَمِ أَشْكَلَ الْعَيْنَيْنِ مَنْهُوشَ الْعَقِبَيْنِ قِيلَ لَسِمَاكٍ: مَا ضَلِيعُ الْفَمِ؟ قَالَ: عَظِيمُ الْفَمِ. قِيلَ: مَا أَشْكَلُ الْعَيْنَيْنِ؟ قَالَ: طَوِيلُ شَقِّ الْعَيْنِ. قِيلَ: مَا مَنْهُوشُ الْعَقِبَيْنِ؟ قَالَ: قليلُ لحم الْعقب. رَوَاهُ مُسلم
