Narrated Abu Hurairah: narrated that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: "I have been ordered to fight the people until they say La Ilaha Illallah", and if they say that, then their blood and wealth will be protected from me, except what it makes obligatory upon them, and their reckoning is up to Allah."

Narrated Abu Hurairah: said: "When the Messenger of Allah ( صلی اللہ علیہ وسلم ) died and Abu Bakr became the Khalifah after him, whoever disbelieved from the Arabs disbelieved, so Umar bin Al-Khattab said to Abu Bakr: 'How will you fight the people while the Messenger of Allah has said: 'I have been ordered to fight the people until they say La Ilaha Illallah, and if they say that, then their blood and wealth will be protected from me, except what it makes obligatory upon them, and their reckoning is with Allah?' So Abu Bakr said: 'By Allah I will fight whoever differentiates between Salat and Zakat. For indeed, Zakat is the right due upon wealth. And by Allah! If they withhold even (camel) tethers which they used to give to the Messenger of Allah ( صلی اللہ علیہ وسلم ) I will fight them for withholding it.' So Umar bin Al-Khattab said: 'By Allah! I saw that Allah had opened Abu Bakr's chest to fighting, so I knew that it was correct.'"

Narrated Anas bin Malik: that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: "I have been ordered to fight the people until they bear witness to La Ilaha Illallah, and that Muhammad is His servant and Messenger, and they face our Qiblah, eat our slaughtered (meat), and perform our Salat. And if they do that, then their blood and wealth will be unlawful to us, except with its due right. For them shall be whatever is for the Muslims, and they shall be obliged with that which the Muslims are obliged."

Narrated Ibn 'Umar: that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: "Islam is based upon five: the testimony of La Ilaha Illallah, and that Muhammad is the Messenger of Allah, the establishment of the Salat, giving the Zakat, fasting (the month of) Ramadan, and performing Hajj to the House."

`With this chain also, a similar hadith is narrated from Ibn Umar (may Allah be pleased with them). Imam Tirmidhi says:
This hadith is Hasan Sahih.

Narrated Abdullah bin Buraidah from Yahya bin Ya'mur who said: "The first person to speak about Al-Qadar was Ma'bad Al-Juhani." He said: "Humaid bin Abdur-Rahman Al-Himyari and I went out until we reached Al-Madinah, and we said: 'If we could only meet someone among the companions of the Prophet ( صلی اللہ علیہ وسلم ) so we could ask him about what those people have innovated." [He said:] "So we met him - meaning Abdullah bin 'Umar - while he was leaving the Masjid." [He said:] "My companion and I were on either side of him." [He said:] I thought my companion was going to leave the speaking to me so I said: "O Abu Abdur-Rahman! There is a group of people who recite the Qur'an and seek knowledge, and they claim there is no Al-Qadar, and that the affair is left to chance.' He said: "Whenever you meet those people, then tell them that I am not of them and they are not of me. By the One Whom Abdullah swears by! If one of them were to spend gold the like of Uhud (mountain) in charity, it would not be accepted from him until he believes in Al-Qadar; the good of it and the bad of it.'" He said: "Then he began to narrate, he said: "'Umar bin Al-Khattab said: "We were with the Messenger of Allah when a man came with extremely white garments, and extremely black hair. He had no appearance of traveling visible on him, yet none of us recognized him. He came until he reached the Prophet ( صلی اللہ علیہ وسلم ). He put his knees up against his knees, and then said: "O Muhammad! What is Iman?' He said 'To believe in Allah, His Angels, His, Books, His Messengers, the Day of Judgement, and Al-Qadar, the good of it and the bad of it.' He said: 'Then what is Islam?' He said: 'Testifying to La Ilaha Illallah, and that Muhammad is His servant and Messenger, establishing the Salat, giving the Zakat, performing Hajj to the House, and fasting (the month of) Ramadan.' He said: 'Then what is Ihsan?' He said 'That (is) you worship Allah as if you see Him, and although you do not see Him, He certainly sees you.' He said: 'For all of those he replied to him: 'You have told the truth.'" He said: "So we were amazed at him, he would ask, and then tell him that he is telling the truth. He said: 'Then when is the Hour?' He ( صلی اللہ علیہ وسلم ) said: 'The one being asked knows no more than the questioner.' He said: 'Then what are its signs?' He said: 'That the slave woman gives birth to her master, and that the naked, poor, and bare-footed shepherds rival each other in the height of the buildings.'" 'Umar said: 'Then the Prophet ( صلی اللہ علیہ وسلم ) met me three days after that and said: 'O 'Umar! Do you know who the questioner was? It was Jibril. He came to teach you about the matters of your religion.'"

A similar hadith is also narrated from Umar bin Khattab (may Allah be pleased with him) through this chain.

‘Through this chain as well,’ a similar hadith is narrated from Umar (may Allah be pleased with him). Imam Tirmidhi says:
1- This hadith is hasan sahih. Through multiple chains, it is also narrated in a similar way from Ibn Umar,
3- Sometimes it has happened that this hadith has come through Ibn Umar, and he narrated it from the Prophet (peace and blessings of Allah be upon him), but the correct version is that Ibn Umar narrates from Umar (may Allah be pleased with him), and Umar (may Allah be pleased with him) narrates from the Prophet (peace and blessings of Allah be upon him),
2- In this chapter, hadiths have also been reported from Talhah bin Ubaidullah, Anas bin Malik, and Abu Hurairah (may Allah be pleased with them).

Narrated Ibn 'Abbas: "A delegation of Abdul-Qais came to the Messenger of Allah ( صلی اللہ علیہ وسلم ) and said: 'We are a tribe from Rabi'ah, and we cannot come to you except during the sacred months. So order us with something that we can take from you, and then we call those who are behind us to it.' So he said: 'I order you with four things: To testify to La Ilaha Illallah, and that I am the Messenger of Allah; to establish the Salat, to give the Zakat, and to give the Khumus from the spoils of war that you gain.'"

‘With this chain also,’ a similar hadith is narrated from Ibn Abbas (may Allah be pleased with them). Imam Tirmidhi says:
1- This hadith is sahih hasan,
2- Shu’bah has also narrated it from Abu Jamrah Nasr bin Imran Duba’i, and in it he has added «أتدرون ما الإيمان شهادة أن لا إله إلا الله وأني رسول الله» “Do you know what faith is? Faith is: to bear witness that there is no deity worthy of worship except Allah, and to bear witness that I am the Messenger of Allah,”and then he narrated the entire hadith.
