Imam in this regard undertook a series of serious discussion in his precious book known as “Forty Hadiths: An Exposition of Ethical and Mystical Traditions”. Imam Khomeini said in this regard as following:
He hated to see his Companions stand up in his respect.
Whenever he entered a gathering, he used to sit in the lowest place He used to dine on the floor and used to sit on the floor
It has been reported from Imam al-Sadiq (PBUH) that the Prophet preferred to ride a donkey without a saddle, preferred to dine in a lowly place with the slaves, and offered alms to beggars with his two hands. That holy personage used to ride a donkey and used to sit on the mount with a slave or some other man.
It is written about him that he used to share with the members of his household the duties of housework himself used to milk the sheep, stitch his own clothes and shoes, grind the flour and knead the dough, and carry his belongings himself.
He liked the company of the poor and the destitute and used to dine with them. Such, and better than what we have described, was the character and the modesty of this great personage, although besides holding his high spiritual station he held to perfection the authority of a temporal sovereign.
Similar was the life and character of ‘Ali ibn Abi Talib (PBUH), who also followed the Prophet’s way, and his character was identical to that of the Prophet.
Imam Khomeini further said:
The Prophet (PBUH), whose knowledge was derived from the Divine Revelation, and whose soul was so great that it could preponderate over the spirits of millions upon millions of human beings, who rejected all the practices and customs of the pagan Arabs, who shattered under his feet all the false creeds, abrogated all the scriptures, and the circle of prophethood achieved its completion in his noble existence; who was the ruler of the world and the hereafter, and who was the master of all the worlds, with the permission of God Almighty; yet his humility towards the creatures of God was more than of any other human being.
