Ali bin Abu Talib reported,

Whenever Ali described the Prophet ﷺ, he would say, "He was neither excessively tall nor noticeably short, but of medium height among his people. His hair was neither tightly curled nor completely straight, but had a gentle wave to it. He was not heavy-set nor was his face overly round, though there was a roundness to it. His complexion was fair with a reddish tinge. His eyes were deep black, and his eyelashes were long. He had broad joints and a wide upper back. His chest was smooth, with a thin line of hair running down the middle. His hands and feet were thick. When he walked, he stepped firmly as though descending a slope. When he turned, he turned his whole body. Between his shoulders was the Seal of Prophethood, for he was the Seal of the Prophets.He was the most generous of people in giving, the most open-hearted, the most truthful in speech, the gentlest in nature, and the noblest in companionship. Whoever saw him for the first time was struck with awe of him, and whoever came to know him closely came to love him."The one describing him would say, "I have never seen anyone like him, before or after."

حدثنا أبو جعفر محمد بن الحسين بن أبي حليمة من قصر الأحنف وأحمد بن عبدة الضبي وعلي بن حجر المعنى واحد قالوا حدثنا عيسى بن يونس حدثنا عمر بن عبد الله مولى غفرة حدثني إبراهيم بن محمد من ولد

علي بن أبي طالب قال

كان علي رضي الله عنه إذا وصف النبي ﷺ قال لم يكن بالطويل الممغط ولا بالقصير المتردد وكان ربعة من القوم ولم يكن بالجعد القطط ولا بالسبط كان جعدا رجلا ولم يكن بالمطهم ولا بالمكلثم وكان في الوجه تدوير أبيض مشرب أدعج العينين أهدب الأشفار جليل المشاش والكتد أجرد ذو مسربة شثن الكفين والقدمين إذا مشى تقلع كأنما يمشي في صبب وإذا التفت التفت معا بين كتفيه خاتم النبوة وهو خاتم النبيين أجود الناس كفا وأشرحهم صدرا وأصدق الناس لهجة وألينهم عريكة وأكرمهم عشرة من رآه بديهة هابه ومن خالطه معرفة أحبه يقول ناعته لم أر قبله ولا بعده مثله
