Allah's Apostle said: Islam is based on (the following) five (principles):

1. To testify that none has the right to be worshipped but Allah and Muhammad is Allah's Apostle.

2. To offer the (compulsory congregational) prayers dutifully and perfectly.

3. To pay Zakat (i.e. obligatory charity) .

4. To perform Hajj. (i.e. Pilgrimage to Mecca)

5. To observe fast during the month of Ramadan.

During the affliction of Ibn Az-Zubair, two men came to Ibn `Umar and said, "The people are lost, and you are the son of `Umar, and the companion of the Prophet, so what forbids you from coming out?" He said, "What forbids me is that Allah has prohibited the shedding of my brother's blood." They both said, "Didn't Allah say, 'And fight then until there is no more affliction?" He said "We fought until there was no more affliction and the worship is for Allah (Alone while you want to fight until there is affliction and until the worship become for other than Allah." Narrated Nafi` (through another group of sub-narrators): A man came to Ibn `Umar and said, "O Abu `Abdur Rahman! What made you perform Hajj in one year and Umra in another year and leave the Jihad for Allah' Cause though you know how much Allah recommends it?" Ibn `Umar replied, "O son of my brother! Islam is founded on five principles, i.e. believe in Allah and His Apostle, the five compulsory prayers, the fasting of the month of Ramadan, the payment of Zakat, and the Hajj to the House (of Allah)." The man said, "O Abu `Abdur Rahman! Won't you listen to why Allah has mentioned in His Book: 'If two groups of believers fight each other, then make peace between them, but if one of then transgresses beyond bounds against the other, then you all fight against the one that transgresses. (49.9) and:--"And fight them till there is no more affliction (i.e. no more worshiping of others along with Allah)." Ibn `Umar said, "We did it, during the lifetime of Allah's Apostle when Islam had only a few followers. A man would be put to trial because of his religion; he would either be killed or tortured. But when the Muslims increased, there was no more afflictions or oppressions." The man said, "What is your opinion about `Uthman and `Ali?" Ibn `Umar said, "As for `Uthman, it seems that Allah has forgiven him, but you people dislike that he should be forgiven. And as for `Ali, he is the cousin of Allah's Apostle and his son-in-law." Then he pointed with his hand and said, "That is his house which you see."

One day while the Prophet was sitting in the company of some people, (The angel) Gabriel came and asked, "What is faith?" Allah's Apostle replied, 'Faith is to believe in Allah, His angels, (the) meeting with Him, His Apostles, and to believe in Resurrection." Then he further asked, "What is Islam?" Allah's Apostle replied, "To worship Allah Alone and none else, to offer prayers perfectly to pay the compulsory charity (Zakat) and to observe fasts during the month of Ramadan." Then he further asked, "What is Ihsan (perfection)?" Allah's Apostle replied, "To worship Allah as if you see Him, and if you cannot achieve this state of devotion then you must consider that He is looking at you." Then he further asked, "When will the Hour be established?" Allah's Apostle replied, "The answerer has no better knowledge than the questioner. But I will inform you about its portents.

1. When a slave (lady) gives birth to her master.

2. When the shepherds of black camels start boasting and competing with others in the construction of higher buildings. And the Hour is one of five things which nobody knows except Allah.

The Prophet then recited: "Verily, with Allah (Alone) is the knowledge of the Hour--." (31. 34) Then that man (Gabriel) left and the Prophet asked his companions to call him back, but they could not see him. Then the Prophet said, "That was Gabriel who came to teach the people their religion." Abu 'Abdullah said: He (the Prophet) considered all that as a part of faith.

Once `Umar bin `Abdul `Aziz sat on his throne in the courtyard of his house so that the people might gather before him. Then he admitted them and (when they came in), he said, "What do you think of Al-Qasama?" They said, "We say that it is lawful to depend on Al-Qasama in Qisas, as the previous Muslim Caliphs carried out Qisas depending on it." Then he said to me, "O Abu Qilaba! What do you say about it?" He let me appear before the people and I said, "O Chief of the Believers! You have the chiefs of the army staff and the nobles of the Arabs. If fifty of them testified that a married man had committed illegal sexual intercourse in Damascus but they had not seen him (doing so), would you stone him?" He said, "No." I said, "If fifty of them testified that a man had committed theft in Hums, would you cut off his hand though they did not see him?" He replied, "No." I said, "By Allah, Allah's Apostle never killed anyone except in one of the following three situations: (1) A person who killed somebody unjustly, was killed (in Qisas,) (2) a married person who committed illegal sexual intercourse and (3) a man who fought against Allah and His Apostle and deserted Islam and became an apostate." Then the people said, "Didn't Anas bin Malik narrate that Allah's Apostle cut off the hands of the thieves, branded their eyes and then, threw them in the sun?" I said, "I shall tell you the narration of Anas. Anas said: "Eight persons from the tribe of `Ukl came to Allah's Apostle and gave the Pledge of allegiance for Islam (became Muslim). The climate of the place (Medina) did not suit them, so they became sick and complained about that to Allah's Apostle. He said (to them ), "Won't you go out with the shepherd of our camels and drink of the camels' milk and urine (as medicine)?" They said, "Yes." So they went out and drank the camels' milk and urine, and after they became healthy, they killed the shepherd of Allah's Apostle and took away all the camels. This news reached Allah's Apostle , so he sent (men) to follow their traces and they were captured and brought (to the Prophet). He then ordered to cut their hands and feet, and their eyes were branded with heated pieces of iron, and then he threw them in the sun till they died." I said, "What can be worse than what those people did? They deserted Islam, committed murder and theft." Then 'Anbasa bin Sa`id said, "By Allah, I never heard a narration like this of today." I ...

One day while Allah's Apostle was sitting with the people, a man came to him walking and said, "O Allah's Apostle. What is Belief?" The Prophet said, "Belief is to believe in Allah, His Angels, His Books, His Apostles, and the meeting with Him, and to believe in the Resurrection." The man asked, "O Allah's Apostle What is Islam?" The Prophet replied, "Islam is to worship Allah and not worship anything besides Him, to offer prayers perfectly, to pay the (compulsory) charity i.e. Zakat and to fast the month of Ramadan." The man again asked, "O Allah's Apostle What is Ihsan (i.e. perfection or Benevolence)?" The Prophet said, "Ihsan is to worship Allah as if you see Him, and if you do not achieve this state of devotion, then (take it for granted that) Allah sees you." The man further asked, "O Allah's Apostle When will the Hour be established?" The Prophet replied, "The one who is asked about it does not know more than the questioner does, but I will describe to you its portents. When the lady slave gives birth to her mistress, that will be of its portents; when the bare-footed naked people become the chiefs of the people, that will be of its portents. The Hour is one of five things which nobody knows except Allah. Verily, the knowledge of the Hour is with Allah (alone). He sends down the rain, and knows that which is in the wombs." (31.34) Then the man left. The Prophet said, "Call him back to me." They went to call him back but could not see him. The Prophet said, "That was Gabriel who came to teach the people their religion." (See Hadith No. 47 Vol 1)

A man came to Allah's Apostle asking him about Islam, Allah's Apostle said, "You have to offer five compulsory prayers in a day and a night (24 hours)." The man asked, "Is there any more compulsory prayers for me?" Allah's Apostle said, "No, unless you like to offer Nawafil (i.e. optional prayers)." Allah's Apostle then added, "You have to observe fasts during the month of Ramadan." The man said, "Am I to fast any other days?' Allah's Apostle said, "No, unless you wish to observe the optional fast voluntarily." Then Allah's Apostle told him about the compulsory Zakat. The man asked, "Do I have to give anything besides?" Allah's Apostle said, "No, unless you wish to give in charity voluntarily." So, the man departed saying, "By Allah I will neither do more nor less than that." Allah's Apostle said, "If he has said the truth he will be successful."

A man from Najd with unkempt hair came to Allah's Apostle and we heard his loud voice but could not understand what he was saying, till he came near and then we came to know that he was asking about Islam. Allah's Apostle said, "You have to offer prayers perfectly five times in a day and night (24 hours)." The man asked, "Is there any more (praying)?" Allah's Apostle replied, "No, but if you want to offer the Nawafil prayers (you can)." Allah's Apostle further said to him: "You have to observe fasts during the month of Ramadan." The man asked, "Is there any more fasting?" Allah's Apostle replied, "No, but if you want to observe the Nawafil fasts (you can.)" Then Allah's Apostle further said to him, "You have to pay the Zakat (obligatory charity)." The man asked, "Is there any thing other than the Zakat for me to pay?" Allah's Apostle replied, "No, unless you want to give alms of your own." And then that man retreated saying, "By Allah! I will neither do less nor more than this." Allah's Apostle said, "If what he said is true, then he will be successful (i.e. he will be granted Paradise)."

On the authority of his father (Sa'd) and his grandfather (Dumayrah) (according to Musa's version) who were present in the battle of Hunayn with the Messenger of Allah (saws): After the advent of Islam, Muhallam ibn Jaththamah al-Laythi killed a man of Ashja'.

That was the first blood-money decided by the Messenger of Allah (saws) (for payment). Uyaynah spoke about the killing of al-Ashja'i, for he belonged to Ghatafan, and al-Aqra' ibn Habis spoke on behalf of Muhallam, for he belonged to Khunduf. The voices rose high, and the dispute and noise grew.

So the Messenger of Allah (saws) said: Do you not accept blood-money, Uyaynah?

Uyaynah then said: No, I swear by Allah, until I cause his women to suffer the same fighting and grief as he caused my women to suffer. Again the voices rose high, and the dispute and noise grew.

The Messenger of Allah (saws) said: Do you not accept the blood-money Uyaynah? Uyaynah gave the same reply as before, and a man of Banu Layth called Mukaytil stood up. He had a weapon and a skin shield in his hand.

He said: I do not find in the beginning of Islam any illustration for what he has done except the one that "some sheep came on, and those in the front were shot; hence those in the rear ran away". (The other example is that) "make a law today and change it."

The Messenger of Allah (saws) said: Fifty (camels) here immediately and fifty when we return to Medina. This happened during some of his journeys. Muhallam was a tall man of dark complexion. He was with the people. They continued (to make effort for him) until he was released. He sat before the Messenger of Allah (saws), with his eyes flowing.

He said: Messenger of Allah! I have done (the act) of which you have been informed. I repent to Allah, the Exalted, so ask Allah's forgiveness for me. Messenger of Allah!

The Messenger of Allah (saws) then said: Did you kill him with your weapon at the beginning of Islam. O Allah! do not forgive Muhallam. He said these words loudly.

AbuSalamah added: He (Muhallam) then got up while he was wiping his tears with the end of his garment.

Ibn Ishaq said: His people alleged that the Messenger of Allah (saws) asked forgiveness for him after that.

Abu Dawud said: Al-Nadr b. Shumail said: al-ghiyar means blood-wit.

(In a dream) I saw myself in a garden, and there was a pillar in the middle of the garden, and there was a handhold at the top of the pillar. I was asked to climb it. I said, "I cannot." Then a servant came and lifted up my clothes and I climbed (the pillar), and then got hold of the handhold, and I woke up while still holding it. I narrated that to the Prophet who said, "The garden symbolizes the garden of Islam, and the handhold is the firm Islamic handhold which indicates that you will be adhering firmly to Islam until you die."
