'Aishah narrated: "We, the family of Muhammad, would go for a month without kindling a fire, having only water and dates."

Anas narrated that the Messenger of Allah (s.a.w) said: "Indeed I have feared for the sake of Allah, such that no one has feared, and I have been harmed for the sake of Allah, such that no one has been harmed. Thirty days and nights have passed over me, and there was no food with Bilal and I forced something with a liver to eat, except what Bilal could conceal under his armpit." This Hadith refers to when the Prophet SAW went out fleeing from Makkah and Bilal was with him. The only food Bilãl had was what he could carry under his arm.

Muhammad bin Ka'b Al-Qurazi said: "Someone narrated to me that he heard 'ali bin abi Talib saying: 'I went out on a cold day from the house of the Messenger of Allah (s.a.w). I had taken a tanned skin, si I tore it in the middle, and out it over my neck, and wrapped my mid-section, fastening it with a palm leave. I was severely hungry, and if there was food in the house of the Messenger of Allah (s.a.w) I would have eaten some of it. I went in search of something. I passed by a Jew on his property drawing water (from a well) with a pulley. I watched him from a gap in the fence. He said: "what is wrong with you O Arab1 Would you like to get a date for every bucket?" I said: "Yes. Open the door so I can come in." He opened the door, I entered and he gave me his bucket. Then for every bucket I pulled out, he would give me a date, until when it was enough for me. I put his bucket down and said: "I think I had enough to eat" then I scooped some water to drink it. Then I came to the Masjid and found the Messenger of Allah (s.a.w) in it.'"

Abu 'Uthman An-Nahdi narrated from Abu Hurairah that they (the Companions) were suffering from hunger so the Messenger of Allah (s.a.w) gave them each a date."

Jabir bin 'Abdullah narrated: "The Messenger of Allah (s.a.w) dispatched us, and there were three-hundred of us. We were carrying our provisions on our shoulders. Then our provisions ran out such that each man among us could eat only a date per day." It was said to him: "O Abu 'Abdullah! How could one date be enough for a man?'" He said: "We realized its value when we did not even have that. Then we came to the sea where we saw a whale that the sea had tossed (on the shore). So we ate as much as we liked from it for eighteen days." Other chains report similar narrations.

Yazid bin Ziyad narrated from Muhammad bin Ka'b Al-Qurazi who heard from Abi Talib narrated that he said: 'I was sitting in a gathering with the Messenger of Allah (s.a.w) when Mus'ab bin 'Umair appeared before us, wearing nothing but a Burdah patched with some animal furs. When the Messenger of Allah (s.a.w) saw him he began crying because of the good life he previously had compared to the state that he was in that day. Then the Messenger of Allah (s.a.w) said: 'How will you people be, when the late morning comes upon one of you while wearing a Hullah, and at the end of the day he is in, (another) Hullah, when a platter is placed in front of him while another is removed, and you cover your houses just as the Ka'bah is covered?' They said: 'O Messenger of Allah! On that day we will be better than we are today, devoting ourselves to worship, satisfied with our good fortune.' So the Messenger of Allah (s.a.w) said: 'No, today you are better than you will be on that day.'"

Abu Hurairah narrated: "The people of As-Suffah were the guests of the people of Islam,they had nothing of people nor wealth to rely upon. And By Allah, the One Whom there is none worthy of worship besides Him – I would lay on the ground on my liver (side) due to hunger, And I would fasten a stone to my stomach out of hunger. One day I sat by the way that they (the Companions) use to come out through. Abu Bakr passed and so I asked him about an Ayah from Allah's Book, not asking him except that he might tell me to follow him (for something to eat). But he passed on without doing so. Then `Umar passed, so I asked him about an Ayah from Allah's Book, not asking him except that he might tell me to follow him. But he passed on without doing so. Then Abul-Qasim (s.a.w) passed, and he smiled when he saw me, and said: 'Abu Hurairah?' I said: 'I am here O Messenger of Allah!' He said: 'Come along.' He continued and I followed him, he entered his house, so I sought permission to enter, and he permitted me. He found a bowl of milk and said: 'Where did this milk come from?' It was said: 'It was a gift to us from so – and – so.' So the Messenger of Allah (s.a.w) said: 'O Abu Hurairah' I said: 'I am here O Messenger of Allah!' He said: 'Go to the people of As-Suffah to invite them.' - Now, they were the guests of the people of Islam, they had nothing of people nor wealth to rely upon. Whenever some charity was brought to him, he would send it to them without using any of it. And when a gift was given to him (s.a.w), he would send for them to participate and share with him in it. I became upset about that, and I said (to myself): 'What good will this bowl be among the people of As-Suffah and I am the one bringing it to them?' Then he ordered me to circulate it among them (So I wondered) what of it would reach me from it, and I hoped that I would get from it what would satisfy me. But I would certainly not neglect to obey Allah and obey His Messenger, so I went to them and invited them. When they entered upon him they sat down. He said: 'Abu Hurairah, take the bowl and give it to them.' So I gave it to a man who drank his fill, then he gave it to another one, until it ended up with the Messenger of Allah (s.a.w), and all of the people had drank their fill. The Messenger of Allah (s.a.w) took the bowl, put it on his hand,then raised his head. He smiled and said: 'Abu Hurairah, drink.' So I drank, then he said: 'Drink.' I kept drinking and he kept on saying, 'Drink.' Then I said: 'By the One Who sent you with the truth! I have no more space for it.' So he took the bowl and praised Allah, mentioned His Name and drank.'”(Sahih)

Yahya Al-Bakka' narrated from Ibn 'Umar who said: "A man belched in the presence of the Prophet(s.a.w), so he said: 'Restain your belching from us. For indeed those who are filled most in the world will be the hungriest on the Day of Judgement.'"

Abu Musa Ash'ari (may Allah be pleased with him) says that he said: O my son! If you had seen us at the time when we were with the Messenger of Allah (peace and blessings of Allah be upon him) and we received rain, you would have thought that our smell was like the smell of sheep. Imam Tirmidhi says:
1- This hadith is authentic,
2- The meaning of this hadith is that the companions' clothes were made of wool, and when rainwater fell on them, they began to smell like sheep.

Abu Hamza narrates that Ibrahim Nakha'i says: Every house, every building, all constructions are a cause of burden. I asked: What is your opinion about the house which is necessary to build? He said: There is neither any reward in it nor any sin.
