Jami` at-Tirmidhi Book 49, Hadith 43
"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.'"
"The Messenger of Allah (ﷺ) had a wide mouth (Dali' Al-Fam), his eyes were Ashkal, and he had thin heals (Manhus Al-'Aqib)."
"I have not seen anything more beautiful than the Messenger of Allah (ﷺ). It was as if the sun flowed upon his face. And I have not seen anyone quicker in his walking than the Messenger of Allah (ﷺ). It was as if the earth was made easy for him. We would be exerting ourselves while he would not be struggling."
