Ibn Majah

´It was narrated that Jabir bin 'Abdullah said:` "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.'"

´It was narrated from Abdullah bin Mas'ud that:` 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."

´It was narrated that 'Aishah said:` "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.'"

´It was narrated that Abu Umamah said:` "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.'"

´It was narrated that Hudhaifah said:` "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."

´It was narrated that 'Abdullah bin 'Abbas said:` "The Messenger of Allah (ﷺ) said: 'Allah refuses to accept the good deeds of one who follows innovation until he gives up that innovation.'"

´It was narrated that Ans bin Malik said:` "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).'"
