Jami` at-Tirmidhi Book 49, Hadith 42
"The Messenger of Allah (ﷺ) had a wide mouth (Dali' Al-Fam), his eyes were Ashkal, and he had thin heals (Manhus Al-'Aqib)."
"The two shins of the Messenger of Allah (ﷺ) were thin, and he would not laugh except as a smile, and whenever I looked at him I would say: "He put kohl on his eyes,' but he (ﷺ) did not use kohl."
"The Messenger of Allah (ﷺ) had a wide mouth (Dali' Al-Fam), his eyes were Ashkal, and he had thin heels (Manhus Al-'Aqib). Shu'bah (one of the narrators) said: "I said to Simak: 'What is "Dali' Al-Fam?"' He said: 'A wide mouth.' I said: 'What is "Ashkal Al-'Ainain?"' He said: 'Having long eyes.'" "I said: 'What is "Manhus Al-'Aqib?"' He said: 'Little flesh.'"
