The Prophet (saws) said: The best number of companions is four, the best number in expeditions four hundred, and the best number in armies four thousand; and twelve thousand will not be overcome through smallness of numbers.

Abu Dawud said: What is correct is that this tradition is mursal (i.e. the link of the Companion is missing).

When Allah's Apostle went to bed, he used to sleep on his right side and then say, "All-ahumma aslamtu nafsi ilaika, wa wajjahtu wajhi ilaika, wa fauwadtu `Amri ilaika, wa alja'tu zahri ilaika, raghbatan wa rahbatan ilaika. La Malja'a wa la manja minka illa ilaika. Amantu bikitabika al-ladhi anzalta wa nabiyyika al-ladhi arsalta! Allah's Apostle said, "Whoever recites these words (before going to bed) and dies the same night, he will die on the Islamic religion (as a Muslim).

The Prophet said "The most superior way of asking for forgiveness from Allah is: O Allah, You are my Lord, there is none worthy of worship except You. You have created me, and I am Your servant, and I am faithful to Your covenant and promise as much as I can. I seek refuge in You from the evil of what I have done. I acknowledge Your blessings upon me, and I admit my sins. So forgive me, for none forgives sins except You.
(Allahumma anta Rabbi la ilaha illa anta, Khalaqtani wa ana `Abduka, wa ana `ala `ahdika wa wa`dika mastata`tu, A`udhu bika min Sharri ma sana`tu, abu'u Laka bini`matika `alaiya, wa abu'u laka bidhanbi faghfir lee fa innahu la yaghfiru adhdhunuba illa anta) "
The Prophet added. "If somebody recites it during the day with firm faith in it, and dies on the same day before the evening, he will be from the people of Paradise; and if somebody recites it at night with firm faith in it, and dies before the morning, he will be from the people of Paradise."

A hadith like this has been narrated on the authority of Humaid with the same chain of transmitters.

The Prophet said, "He (a Muslim) who dies of an abdominal disease is a martyr, and he who dies of plague is a martyr."

The Prophet did not eat at a table till he died, and he did not eat a thin nicely baked wheat bread till he died.

We went to pay a visit to Khabbab (who was sick) and he had been branded (cauterized) at seven places in his body. He said, "Our companions who died (during the lifetime of the Prophet) left (this world) without having their rewards reduced through enjoying the pleasures of this life, but we have got (so much) wealth that we find no way to spend It except on the construction of buildings Had the Prophet not forbidden us to wish for death, I would have wished for it.' We visited him for the second time while he was building a wall. He said, A Muslim is rewarded (in the Hereafter) for whatever he spends except for something that he spends on building."

When Negus died, the Prophet said, "Today a pious man has died. So get up and offer the funeral prayer for your brother Ashama."

Allah's Apostle said, "Anyone who dies worshipping others along with Allah will definitely enter the Fire." I said, "Anyone who dies worshipping none along with Allah will definitely enter Paradise."

A man came to the Prophet and said, "O Allah's Apostle! My mother died and she ought to have fasted one month (for her missed Ramadan). Shall I fast on her behalf?" The Prophet replied in the affirmative and said, "Allah's debts have more right to be paid." In another narration a woman is reported to have said, "My sister died..." Narrated Ibn `Abbas: A woman said to the Prophet "My mother died and she had vowed to fast but she didn't fast." In another narration Ibn `Abbas is reported to have said, "A woman said to the Prophet, "My mother died while she ought to have fasted for fifteen days."

Anas b. Malik reported that Allah's Messenger (may peace be upon him) died when he was sixty-three years old, and so was the case with Abu Bakr, and so was the case with Umar who was also sixty-three (when he died).

Allah's Apostle said, "While a man was going on a way, he saw a thorny branch and removed it from the way and Allah became pleased by his action and forgave him for that." Then the Prophet said, "Five are martyrs: One who dies of plague, one who dies of an Abdominal disease, one who dies of drowning, one who is buried alive (and) dies and one who is killed in Allah's cause." (The Prophet further said, "If the people knew the reward for pronouncing the Adhan and for standing in the first row (in the congregational prayer) and found no other way to get it except by drawing lots they would do so, and if they knew the reward of offering the Zuhr prayer early (in its stated time), they would race for it and if they knew the reward for `Isha' and Fajr prayers in congregation, they would attend them even if they were to crawl.

The Prophet said one statement and I said another. The Prophet said "Whoever dies while still invoking anything other than Allah as a rival to Allah, will enter Hell (Fire)." And I said, "Whoever dies without invoking anything as a rival to Allah, will enter Paradise."

Allah's Apostle said, "I am more closer to the believers than their ownselves, so whoever (among them) dies leaving some inheritance, his inheritance will be given to his 'Asaba, and whoever dies leaving a debt or dependants or destitute children, then I am their supporter."

The Prophet said, "There is no Diya for a person injured or killed by an animal (going about without somebody to control it) and similarly, there is no Diya for the one who falls and dies in a well, and also the one who dies in a mine. As regards the Ar-Rikaz (buried wealth), one-fifth thereof is for the state."
