The Prophet of Allah, sallallaahu ‘alayhi wa sallam, was concerned about the living conditions of his Companions

“I came out on a winter day from the house of the Prophet of Allah, sallallaahu ‘alayhi wa sallam, hungry and very cold. I took a skin that was missing some hair, put my head through it and then tied the rest around me and tightened it with a palm leaf so I could stay warm. I was extremely hungry, and if there was any food in the house of the Prophet of Allah, sallallaahu ‘alayhi wa sallam, I would have eaten it. I left to search for food, and I passed by a Jew in his land who was getting water from his well. I looked at him through an opening in the wall. He said to me, ‘What is the matter with you, O Bedouin? Would you want to draw water and for every bucket you will get one date?’ I said: ‘Yes, open the door so I may enter.’ He opened it, I entered and he gave me the bucket. Every time I filled it, he would give me a date. When I got a handful, I left the bucket and said: ‘That is enough for me.’ So I ate them and then drank from the water. I then came to the mosque and found the Prophet of Allah, sallallaahu ‘alayhi wa sallam, there. While we were sitting with the Messenger of Allah, sallallaahu ‘alayhi wa sallam, in the mosque, Mus’ab ibn Umayr came wearing only a cloak patched with fur. When the Messenger of Allah, sallallaahu ‘alayhi wa sallam, saw him he cried, because of his former life of luxury and how was living then. He, sallallaahu ‘alayhi wa sallam, then said: “How will it be with you when one of you goes out in the morning wearing a garment, and goes out in the end of the day wearing another? When one dish is placed before him and another is lifted up [meaning there will be much food], and you cover your houses just as the Ka’bah is covered?” They said: “O Messenger of Allah, sallallaahu ‘alayhi wa sallam, we shall be better on that day, we can free our time for worship, and our needs will be taken care of.” He, sallallaahu ‘alayhi wa sallam, said: “Indeed, you are better today than you will be at that time.”Meaning, that the matter is not as you said: because a rich person is usually busy with his wealth and would not seclude himself and devote himself for worship. Unlike the person who only has what suffices him, because the former would be busy earning and collecting wealth, while the latter would have the time to devote to worship.
