Chapter 5: He who narrated (a Hadith) from the Messenger of Allah (saws) when he considers it to be false
The Prophet (ﷺ) said: "Whoever narrates a Hadith from me thinking it to be false, then he is one of the two liars."Another chain similar to the narration of Samurah bin Jundub.
The Messenger of Allah (ﷺ) said: '"Whoever narrates a Hadith from me thinking it to be false, then he is one of the two liars."
Chapter 6: Following the way of the Rightly Guided Caliphs
I heard 'Irbad bin Sariyah say: 'One day, the Messenger of Allah (ﷺ) stood up among us and delivered a deeply moving speech to us that melted our hearts and caused our eyes to overflow with tears. It was said to him: 'O Messenger of Allah, you have delivered a speech of farewell, so enjoin something upon us.' He said: 'I urge you to fear Allah, and to listen and obey, even if (your leader) is an Abyssinian slave. After I am gone, you will see great conflict. I urge you to adhere to my Sunnah and the path of the Rightly-Guided Caliphs, and cling stubbornly to it. And beware of newly-invented matters, for every innovation is a going astray.'"
He heard Al-'Irbad bin Sariyah say: "The Messenger of Allah (ﷺ) delivered a moving speech to us which made our eyes flow with tears and made our hearts melt. We said: 'O Messenger of Allah. This is a speech of farewell. What did you enjoin upon us?' He said: 'I am leaving you upon a (path of) brightness whose night is like its day. No one will deviate from it after I am gone but one who is doomed. Whoever among you lives will see great conflict. I urge you to adhere to what you know of my Sunnah and the path of the Rightly-Guided Caliphs, and cling stubbornly to it. And you must obey, even if (your leader is) an Abyssinian leader. For the true believer is like a camel with a ring in its nose; wherever it is driven, it complies."
"The Messenger of Allah (ﷺ) led us in Fajr (morning) prayer, then he turned to us and delivered an eloquent speech". And he mentioned something similar (as no.43)
Chapter 7: Avoiding Bid'ah (innovation) and dispute
"When the Messenger of Allah (ﷺ) delivered a sermon, his eyes would turn red, he would raise his voice and he would speak with intensity, as if he were warning of an (enemy) army, saying, 'They will surely attack you in the morning, or they will surely attack you in the evening!' He would say: 'I and the Hour have been sent like these two,' and he would hold his index and middle finger. Then he would say: 'The best of guidance is the guidance of Muhammad. The most evil matters are those that are newly-invented, and every innovation (Bid'ah) is a going astray.' And he used to say: 'Whoever dies and leaves behind some wealth, it is for his family, and whoever leaves behind a debt or dependent children, then they are both my responsibility.'"
the Messenger of Allah (ﷺ) said: "Verily there are two things - words and guidance. The best words are the words of Allah, and the best guidance in the guidance of Muhammad. Beware of newly-invented matters, for every newly-invented matter is an innovation (Bid'ah) and every innovation is a going-stray. Do not let the desire for a long life causes your hearts to grow hard. That which is bound to happen is close to you, and the only thing that is far away is that which is not going to happen. The one who is doomed to Hell is doomed from his mother's womb, and the one who is destined for Paradise is the one who learns from the lessons of others. Killing a believer constitutes disbelief (Kufr) and verbally abusing him is immorality (Fusuq). It is not permissible for a Muslim to forsake his brother for more than three days. Beware of lying, for lying is never good, whether it is done seriously or in jest. A man should not make a promise to a child that he will not keep. Lying leads to immorality and immorality leads to Hell. Truthfulness leads to righteousness and righteousness leads to Paradise. It will be said of the truthful person: 'He spoke the truth and was righteous', and it will be said of the liar, 'He told lies and was immoral.' "For a person continues to tell lies until he is recorded with Allah as a liar."
"The Messenger of Allah (ﷺ) recited the following Verse: 'It is He Who has sent down to you (Muhammad) the Book (this Qur'an). In it are verses that are entirely clear, they are the foundations of the Book; and others not entirely clear (up to His saying: ) 'And none receive admonition except men of understanding.' Then he said: 'O 'Aishah, if you see those who dispute concerning it (the Qur'an), they are those whom Allah has referred to here, so beware of them.'"
"The Messenger of Allah (ﷺ) said: 'No people go astray after having followed right guidance, but those who indulge in disputes.' Then he recited the Verse: "Nay! But they are a quarrelsome people.'"
"The Messenger of Allah (ﷺ) said: 'Allah will not accept any fasting, prayer, charity, Hajj, 'Umrah, Jihad, or any other obligatory or voluntary action from a person who follows innovation (Bid'ah). He comes out of Islam like a hair pulled out of dough."
"The Messenger of Allah (ﷺ) said: 'Allah refuses to accept the good deeds of one who follows innovation until he gives up that innovation.'"
"The Messenger of Allah (ﷺ) said: 'Whoever gives up telling lies in support of a false claim, a palace will be built for him in the outskirts of Paradise. Whoever gives up argument when he is in the right, a palace will be built from him in the middle (of Paradise). And whoever had good behavior, a palace will be built for him in the highest reaches (of Paradise).'"
Chapter 8: Avoiding individual opinion and analogy (with regard to matters of religion)
the Messenger of Allah (ﷺ) said: 'Allah will not take away knowledge by removing it from people (from their hearts). Rather He will take away knowledge by taking away the scholars, then when there are no scholars left, the people will take the ignorant as their leaders. They will be asked questions and they will issue verdicts without knowledge, thus they will go astray and lead others astray.'"
"The Messenger of Allah (ﷺ) said: 'Whoever is given a Fatwa (verdict) that has no basis, then his sin will be upon the one who issued that Fatwa.'"
"The Messenger of Allah (ﷺ) said: 'Knowledge is based on three things, and anything beyond that is superfluous: a clear Verse, an established Sunnah, or the rulings by which the inheritance is divided fairly.'"
"When the Messenger of Allah (ﷺ) sent me to Yemen, he said: 'Do not pass any judgment or make any decision except on the basis of what you know. If you are uncertain about a matter, wait until you understand it fully, or write to me concerning it.'" (Maudu')
"I heard the Messenger of Allah (ﷺ) say: 'The affairs of the Children of Israel remained fair until Muwalladun emerged among them - the children of female slaves from other nations. They spoke of their own opinions (in religious matters) and so they went astray and led others astray.'"
Chapter 9: Regarding Faith
"The Messenger of Allah (ﷺ) said: 'Faith has sixty-some or seventy parts, the least of which is to remove a harmful thing from the road and the greatest of which is to say La ilaha illalah (none has the right to be worshipped but Allah). And modesty is a branch of faith.'"Another chain from Abu Hurairah, from the Prophet (ﷺ) with similar wording.
"The Messenger of Allah (ﷺ) said heard a man urging his brother to be modest. He said: 'Indeed modesty is a branch of faith.'"
"The Messenger of Allah (ﷺ) said: 'No one will enter Paradise who has even a mustard-seed's weight of arrogance in his heart, and no one will enter Hell who has even a mustard-seed's weight of faith in his heart.'"
