The attitude of the rich Sahaabah towards helping the Prophet (blessings and peace of Allah be upon him) by supplying food

There are several hadis mentioned which says that our prophet (pbuh)
suffered from hunger. For example, Aisha (r) mentioned, Muhammad
(pbuh) and his family never got enough bread to satisfy their hunger
for two days before He died. (Bukhari and Muslim). Numan Ibn Bashir
(r) said, I have seen your prophet (s) that, He never got old or
rotten dates to satisfy Hishunger. (Muslim). My question is, isnt
there any Sahaba around our prophet (s) who can provide Him food?
Usman (r) was a rich Sahaba, as far I know. Isn't it a duty of a
Muslimto take care of other Muslims, especially if it was our beloved
prophet (s)? Can you please explain?.
Praise be to Allaah.
Firstly:
The Messenger of Allah (blessings and peace of Allah be upon him) was
the most ascetic of people; Allah did not allow any room for love of
worldly matters in his heart or let him regard such matters as being
of any importance. Ahmad (7120) narrated from Abu Hurayrah that he
said: Jibreel sat with the Prophet (blessings and peace of Allah be
upon him) and looked at the sky, and he saw an angeldescending.
Jibreel said: This angel has never descended since he was created,
until now. When he came down, hesaid: O Muhammad, your Lord has sent
me to you and He says: Shall He make you a Prophet-king or a
Messenger-slave? Jibreel said: Be humble before your Lord, O Muhammad.
He said: "Rather a Messenger-slave."

Al-Baghawi narrated in Sharh as-Sunnah (5/442)that 'Aa'ishah said: I
said:O Messenger of Allah, may Allah cause me to besacrificed for you,
eat reclining for it will be easier for you. He tilted his head until
his forehead nearly touchedthe ground and said: "No; rather I shall
eat as a slave eats and I shall sitas a slave sits."
Classed as saheeh by al-Albaani in as-Saheehah, 544.
The hadeeths which speak of his asceticism and lack of interest in
worldly accumulation and adornment are too numerous to be counted.
For a discussion of that and further explanation of his asceticism,

Secondly:
The situation of most of his Companions at the beginning of Islam was
like his or close to it. Thisis explained by the report narrated by
al-Bukhaari (4242) from 'Aa'ishah (may Allah be pleased with her) who
said: When Khaybar was conquered, we said: Now we will eat our fill of
dates.
Al-Haafiz (may Allah havemercy on him) said:
This indicates that before that they were living on very little. End quote.
And he also said:
The fact of the matter is that many of them lived a life of hardship
before the Hijrah when they were in Makkah, then when they migrated to
Madinah, most of them were still like that and the Ansaar helped them
by giving them accommodation and in other ways. When they were enabled
to conquer an-Nadeer and after that, they returned the favour. End
quote.
When they became better off, they focused on spending in charity,
equipping armies and other kinds of good deeds. Some of them gave all
their wealth, some of them gave half of their wealth, some of them
would equip fighters who were goingout on campaign or takecare of
their families in their absence. This worldwas not their interest and
it never crossed their minds. Ahmad narrated in az-Zuhd (p. 36) that
Sa'eed ibn Jubayr said: 'Abd ar-Rahmaan ibn 'Awf (may Allah be pleased
with him) – who was one of the wealthy Sahaabah – could not
berecognised from among his slaves.
Thirdly:
No one should think thatthe Sahaabah did not pay attention to the
situation of the Messenger of Allah (blessings and peace of Allah be
upon him) or that they were heedless concerning it, even though they
knew that ifhe wanted to, he could have prayed to Allah, may He be
exalted, and He would have made him very rich. In fact they (may Allah
be pleased with them) usedto help him by giving him gifts and offering
him hospitality, especially the Ansaar. Al-Bukhaari (2567) and Muslim
(2972) narrated from 'Aa'ishah (may Allah be pleased with her) that
she said to 'Urwah: O son of my sister, we used to look atthe crescent
moon, then the crescent moon, then the crescent moon, threecrescent
moons in two months, and no fire would be lit in the houses of the
Messenger of Allaah (blessings and peace of Allah be upon him). I
said: O aunt, whatdid you live on? She said: The two black ones,dates
and water, but theMessenger of Allaah (blessings and peace of Allah be
upon him) had some neighbours from among the Ansaar and they had
milch-animals, and they would send some of their milk to theMessenger
of Allaah (blessings and peace of Allah be upon him), and he would
give it to us to drink.
And al-Bukhaari (2574) and Muslim (2441) narrated from 'Aa'ishah (may
Allah be pleased with her) that the people used to send their gifts
when it was 'Aa'ishah's day, seeking thereby to please the Messenger
of Allaah (blessings and peace of Allah be upon him).
And there are many similar hadeeths.
It was narrated from 'Aa'ishah (may Allah be pleased with her) that
they slaughtered a sheep and the Prophet (blessings and peace of Allah
be upon him) said: "What is left of it?" She said: There is nothing
left of it except a shoulder. He said: "All of it is left except the
shoulder!"
Narrated by Ahmad, 2372; at-Tirmidhi, 2470. He said: A saheeh hadeeth.
The members of his noble household followed his example in that
regard, to the extent that they forgot their own share compared to
what they gave to other people, as they gave them precedence over
themselves.
It was narrated from Hishaam ibn 'Urwah, from his father, that
Mu'aawiyah ibn Abi Sufyaan sent one hundred thousand (i.e., money) to
'Aa'ishah (may Allah be pleased with her), and she shared it out until
there was nothing left of it. Bareerah said: You are fasting; why did
you not buy a dirham's worth of meat for us? 'Aa'ishah said: If I had
been reminded, I would have done that.
