His asceticism and humility ﷺ

The simplicity of his life ﷺ

Aisha, may Allah be pleased with her, said: "The family of Muhammad ﷺ did not have enough barley bread to be satisfied for two successive days until the Messenger of Allah ﷺ was taken." — narrated by al-Bukhari and Muslim [al-Bukhari wa Muslim]. And Anas, may Allah be pleased with him, said: "The Messenger of Allah ﷺ never ate from a dining cloth (khawan) nor ate refined/whitened bread until he died." — narrated by al-Bukhari [al-Bukhari].

The Messenger of Allah ﷺ did not see sifted white bread until he met Allah — narrated by al-Bukhari from Sahl ibn Sa'd [al-Bukhari 'an Sahl ibn Sa'd]
Aisha, may Allah be pleased with her, said: "By Allah, he never ate his fill of bread and meat twice in one day." — narrated by al-Tirmidhi [al-Tirmidhi].
He ﷺ mended his garment with his own hand, patched his sandals himself, and rode a donkey — narrated by Ahmad [Ahmad].
His bed ﷺ was of adam (leather) stuffed with palm-fiber — narrated by al-Tirmidhi in ash-Shama'il [al-Tirmidhi (ash-Shama'il)].
He ﷺ left no wealth to his heirs except his mule, his weapon, and a piece of land which he made sadaqah (charitable gift).
He would serve his household at home, milk the sheep, and assist with household affairs.

His humility ﷺ toward people

He ﷺ was the humblest of people despite the greatness of his station; he sat with the poor and the needy and visited them, accepted the invitation of a servant, and walked with the widow and the orphan to attend to their needs. And when he sat in a gathering no distinction was made between him and his companions, so a stranger would not recognize him until he asked.

He would accept the invitation of a free person, a slave, or a bonded servant.
He would visit the sick, follow the funeral procession, and accept invitations.
He would accompany widows and orphans in their needs.
He did not raise himself above his companions in a gathering.
He would greet the younger before the older.
He would shake hands with whoever he met and would not withdraw his hand until the other withdrew first.

His generosity ﷺ

He ﷺ was the most generous of people, and he was most generous in Ramadan when he met Jibril; his generosity ﷺ was stronger than a rushing wind — [Muttafaqun 'alayh]. And he ﷺ was never asked for anything and said: 'No.' And when he was given money he would distribute it all before evening.

The most generous of people — and he was most generous in Ramadan
His generosity was stronger than a rushing wind — [Muttafaqun 'alayh 'an Ibn Abbas]
He was never asked and said no — if he had it he gave, and if he did not have it he promised.
He would distribute all the money before evening.
