When the Prophet died and Abu Bakr became his successor and some of the Arabs reverted to disbelief, `Umar said, "O Abu Bakr! How can you fight these people although Allah's Apostle said, 'I have been ordered to fight the people till they say: 'None has the right to be worshipped but Allah, 'and whoever said, 'None has the right to be worshipped but Allah', Allah will save his property and his life from me, unless (he does something for which he receives legal punishment) justly, and his account will be with Allah?' "Abu Bakr said, "By Allah! I will fight whoever differentiates between prayers and Zakat as Zakat is the right to be taken from property (according to Allah's Orders). By Allah! If they refused to pay me even a kid they used to pay to Allah's Apostle, I would fight with them for withholding it." `Umar said, "By Allah: It was nothing, but I noticed that Allah opened Abu Bakr's chest towards the decision to fight, therefore I realized that his decision was right."

When Allah's Apostle died and Abu Bakr became the caliph some Arabs renegade (reverted to disbelief) (Abu Bakr decided to declare war against them), `Umar, said to Abu Bakr, "How can you fight with these people although Allah's Apostle said, 'I have been ordered (by Allah) to fight the people till they say: "None has the right to be worshipped but Allah, and whoever said it then he will save his life and property from me except on trespassing the law (rights and conditions for which he will be punished justly), and his accounts will be with Allah.' " Abu Bakr said, "By Allah! I will fight those who differentiate between the prayer and the Zakat as Zakat is the compulsory right to be taken from the property (according to Allah's orders) By Allah! If they refuse to pay me even a she-kid which they used to pay at the time of Allah's Apostle . I would fight with them for withholding it" Then `Umar said, "By Allah, it was nothing, but Allah opened Abu Bakr's chest towards the decision (to fight) and I came to know that his decision was right."

Allah 's Apostle said, " I have been ordered to fight with the people till they say, 'None has the right to be worshipped but Allah,' and whoever says, 'None has the right to be worshipped but Allah,' his life and property will be saved by me except for Islamic law, and his accounts will be with Allah, (either to punish him or to forgive him.)"

Allah's Apostle said, "I have been ordered to fight the people till they say: 'None has the right to be worshipped but Allah.' And if they say so, pray like our prayers, face our Qibla and slaughter as we slaughter, then their blood and property will be sacred to us and we will not interfere with them except legally and their reckoning will be with Allah."

Allah's Apostle said: "I have been ordered (by Allah) to fight against the people until they testify that none has the right to be worshipped but Allah and that Muhammad is Allah's Apostle, and offer the prayers perfectly and give the obligatory charity, so if they perform that, then they save their lives and property from me except for Islamic laws and then their reckoning (accounts) will be done by Allah."

When Allah's Apostle died and Abu Bakr was elected as a Caliph after him, some of the Arabs reverted to disbelief, `Umar said to Abu Bakr, "How dare you fight the people while Allah's Apostle said, I have been ordered to fight the people till they say 'None has the right to be worshipped but Allah' And whoever says: None has the right to be worshipped but Allah.' waves his wealth and his life from me unless he deserves a legal punishment lusty, and his account will be with Allah! Abu Bakr said, "By Allah, I will fight him who discriminates between Zakat and prayers, for Zakat is the Compulsory right to be taken from the wealth By Allah, if they refuse to give me even a tying rope which they use to give to Allah's Apostle, I would fight them for withholding it." `Umar said, 'By Allah, It was nothing, except I saw that Allah had opened the chest of Abu Bakr to the fight, and I came to know for certain that was the truth."

The day of Bu'ath (i.e. Day of fighting between the two tribes of the Ansar, the Aus and Khazraj) was brought about by Allah for the good of His Apostle so that when Allah's Apostle reached (Medina), the tribes of Medina had already divided and their chiefs had been killed and wounded. So Allah had brought about the battle for the good of H is Apostle in order that they (i.e. the Ansar) might embrace Islam.

I witnessed Al-Miqdad bin Al-Aswad in a scene which would have been dearer to me than anything had I been the hero of that scene. He (i.e. Al-Miqdad) came to the Prophet while the Prophet was urging the Muslims to fight with the pagans. Al-Miqdad said, "We will not say as the People of Moses said: Go you and your Lord and fight you two. (5.27). But we shall fight on your right and on your left and in front of you and behind you." I saw the face of the Prophet getting bright with happiness, for that saying delighted him.

The Prophet said, "An honest Muslim storekeeper who carries out the orders of his master and pays fully what he has been ordered to give with a good heart and pays to that person to whom he was ordered to pay, is regarded as one of the two charitable persons."

There was revealed: 'Not equal are those believers who sit (at home) and those who strive and fight in the Cause of Allah.' (4.95) The Prophet said, "Call Zaid for me and let him bring the board, the inkpot and the scapula bone (or the scapula bone and the ink pot)."' Then he said, "Write: 'Not equal are those Believers who sit..", and at that time `Amr bin Um Maktum, the blind man was sitting behind the Prophet . He said, "O Allah's Apostle! What is your order For me (as regards the above Verse) as I am a blind man?" So, instead of the above Verse, the following Verse was revealed: 'Not equal are those believers who sit (at home) except those who are disabled (by injury or are blind or lame etc.) and those who strive and fight in the cause of Allah.' (4.95)

A man came to the Prophet and asked, "A man fights for war booty; another fights for fame and a third fights for showing off; which of them fights in Allah's Cause?" The Prophet said, "He who fights that Allah's Word (i.e. Islam) should be superior, fights in Allah's Cause."

This tradition has been transmitted on the authority of Shu'ba through A'mash, but there is a difference of order of the four.

That heard Allah's Apostle saying, "We are the last but will be the foremost to enter Paradise)." The Prophet added, "He who obeys me, obeys Allah, and he who disobeys me, disobeys Allah. He who obeys the chief, obeys me, and he who disobeys the chief, disobeys me. The Imam is like a shelter for whose safety the Muslims should fight and where they should seek protection. If the Imam orders people with righteousness and rules justly, then he will be rewarded for that, and if he does the opposite, he will be responsible for that."

Allah's Apostle sent us (to fight) against Al-Huraqa (one of the sub-tribes) of Juhaina. We reached those people in the morning and defeated them. A man from the Ansar and I chased one of their men and when we attacked him, he said, "None has the right to be worshipped but Allah." The Ansari refrained from killing him but I stabbed him with my spear till I killed him. When we reached (Medina), this news reached the Prophet. He said to me, "O Usama! You killed him after he had said, 'None has the right to be worshipped but Allah?"' I said, "O Allah's Apostle! He said so in order to save himself." The Prophet said, "You killed him after he had said, 'None has the right to be worshipped but Allah." The Prophet kept on repeating that statement till I wished I had not been a Muslim before that day.

The Prophet said, "We have been ordered to prostrates on seven bones and not to tuck up the clothes or hair."

The Prophet said, "I have been ordered to prostrate on seven (bones) and not to tuck up the hair or garment."

A bedouin asked the Prophet, "A man may fight for the sake of booty, and another may fight so that he may be mentioned by the people, and a third may fight to show his position (i.e. bravery); which of these regarded as fighting in Allah's Cause?" The Prophet said, "He who fights so that Allah's Word (i.e. Islam) should be superior, fights for Allah's Cause."

A man came to the Prophet and said, "A man fights for pride and haughtiness another fights for bravery, and another fights for showing off; which of these (cases) is in Allah's Cause?" The Prophet said, "The one who fights that Allah's Word (Islam) should be superior, fights in Allah's Cause." (See Hadith No. 65, Vol. 4)

That Al-Ash'ath entered upon him while he was eating. Al-Ash'ath said, "Today is 'Ashura." I said (to him), "Fasting had been observed (on such a day) before (the order of compulsory fasting in) Ramadan was revealed. But when (the order of fasting in) Ramadan was revealed, fasting (on 'Ashura') was given up, so come and eat."

Ibn `Umar came to us and a man said (to him), "What do you think about 'Qit-alal-Fitnah' (fighting caused by afflictions)." Ibn `Umar said (to him), "And do you understand what an affliction is? Muhammad used to fight against the pagans, and his fighting with them was an affliction, (and his fighting was) not like your fighting which is carried on for the sake of ruling."
