Rasulullah (Sallaahu alayhi wasallam)’s description,
condensed from the Ahaadeeth of Shamaa`il Tirmizi
When Rasulullah (Sallallaahu 'alayhi wasallam) walked, he leaned forward slightly - with a slight forward inclination of the head and shoulders. When he walked, he lifted his legs with vigour, as if he were descending to a low-lying place, and would place his feet softly on the ground.
He walked at a quick pace and took a rather long step. He did not take small steps.
(He did not walk with his chest pushed out in pride, nor did he drag his feet.)
While walking, he asked the Sahabah to walk in front, and he himself walked behind. (This was his humbleness).
He made Salaam first, to whomsoever he met.
When he looked at something, he turned his whole body towards it.
When he addressed a person, he turned his whole body towards that person. He did not only turn his face towards the person he addressed, as this is considered impolite, and sometimes even denotes pride. Rasulullah (Sallaahu alayhi wasallam) faced the person with his chest and body.
He always looked down. His Mubarak sight was focussed more to the ground than towards sky.
(Eventhough his Mubarak habit was to look down towards the ground, whilst waiting for Wahi, he would also look towards the sky. ...Usually, he looked down, on the ground.)
He would look with a light eye (i.e. he looked at a thing with modesty and bashfulness; hence he did not stare at anything.)
