Rabee'ah ibn Abi 'Abd al-Rahmaan said: "I heard Anas ibn Maalik (may Allaah be pleased with him) describing the Prophet (peace and blessings of Allaah be upon him). He said: 'He was of average height, not too tall and not too short, with a pinkish colour, not very white and not dark, and his hair was neither very curly nor very straight. The Revelation came to him when he was forty years old, and he stayed in Makkah for ten years after the Revelation came, then in Madeenah for ten years. When he died, there were no more than twenty white hairs on his head and in his beard." (al-Bukhaari, 3283).
Al-Baraa' ibn 'Aazib said: "The Messenger of Allaah (peace and blessings of Allaah be upon him) was broad shouldered and had thick hair coming down to his shoulders and earlobes. He was wearing red garments. I have never seen anything more beautiful than him." (Reported by Muslim, Kitaab al-Fadaa'il, Baab Sifat Sha'r al-Nabi (peace and blessings of Allaah be upon him), no. 2338).
'Ali said: "He was neither tall nor short, and had large hands and feet. He had a large head and was big-boned, and the thin line of hair (starting from his chest and extending to the navel) was long. When he walked, he would lean forward, as if he was walking downhill. I have never seen anyone like him, before or since." (Reported by al-Tirmidhi, 3570, who said this is a saheeh hasan hadeeth).
Jaabir ibn Samurah said: "The Messenger of Allaah (peace and blessings of Allaah be upon him) was dalee' al-fam, ashkal al-'ayn and manhoos al-'aqib." Shu'bah said: "I asked Maalik, 'What is dalee' al-fam?' He said: 'Wide-mouthed.' I asked, 'What is ashkal al-'ayn?' He said, 'Big-eyed.' I asked, 'What is manhoos al-'aqib?' He said, 'His heels were not fleshy.'" (Saheeh Muslim, Kitaab al-Fadaa'il, 2339).
As for the sin which you committed in the house of your brothers, repent to Allaah for this. If you took something that belongs to them, then give it back. And Allaah is All-Forgiving, Most Merciful
