ccording to his son-in-law, Ali, the Prophet was of middle height and sturdy build. His head was large, his complexion healthy; with smooth cheeks, a thick beard, and wavy hair. When he was vexed, a vein swelled out on his forehead, from the top of his aquiline nose between his eyebrows which were well arched and meeting.
His big eyes, framed by long lashes, were of a deep black, lit up at times by a few red gleams, and his glance was extraordinarily keen. His mouth was large, well suited to eloquence. His teeth, as white as hailstones, were slightly separated in front. The palms of his hands, of which the fingers were long and slender, were broad and soft to the touch like fine silk.
The Seal of Prophecy—which the monk Bahira discovered—was just below the nape of the neck, between Mohammad's shoulder-blades. It resembled the scar left by the bite of a leech, and was of a reddish hue, surrounded by a few hairs.
The Prophet's gait was slow, solemn and majestic. In all circumstances, he never lost his presence of mind and was quick-witted. When he turned round, the whole of his body moved, unlike frivolous folks twisting their necks and rolling their heads about. If he held out an object to show it, he made use of the whole of his hand and not two or three fingers. When surprised, he glorified Allah, turning the palms of his hands to heaven, nodding his head and biting his lips.
When he made an affirmation, he struck his widely-open left hand with his right thumb to lay stress on his declaration. If angry, his face flushed; he stroked his beard and passed his hand over his face, taking a deep breath and exclaiming: 'I leave it to Allah, the best proxy!'
He was a man of few words; but each had many different meanings, some plain and others hidden. As for the charm of his elocution, it was supernatural, going straight to the heart. None could resist it. The Prophet's merriment never went beyond a smile, but if he was overcome by an excess of gaiety, he covered his mouth with his hand.
His disposition was even, without self-sufficiency or obstinacy. Whenever any of his companions called him, he replied immediately: 'Here I am!' He liked to play with their children and would press them to his noble breast. He used to make the sons of his uncle Abbas stand in a row and, promising to reward the child who got first to him, they would all run into his arms and jump on his knees.
He interested himself in the doings of all, whether slaves or nobles, and followed the funeral of the most humble Believer. He flew one day into a most violent passion because, through negligence, he had not been apprised of the death of a poor negro who swept out the Mosque. He insisted on being told where the grave was situated and went to pray over it.
When an applicant tried to get close to the Prophet's ear so as not to be overheard, he would bend his head until the man had finished speaking. When a visitor took the hand of Mohammad, he was never the first to withdraw it, but waited until the other chose to relax his grasp. The Prophet often said: 'To be a good Mussulman, we must wish for others that which we wish for ourselves.'
