Sunan Abi Dawud

When your companion dies, leave him and do not revile him.

The Prophet (ﷺ) said: Make a mention of the virtues of your dead, and refrain from (mentioning) their evils.

I heard the Messenger of Allah (ﷺ) say: There were two men among Banu Isra'il, who were striving for the same goal. One of them would commit sin and the other would strive to do his best in the world. The man who exerted himself in worship continued to see the other in sin. He would say: Refrain from it. One day he found him in sin and said to him: Refrain from it. He said: Leave me alone with my Lord. Have you been sent as a watchman over me? He said: I swear by Allah, Allah will not forgive you, nor will he admit you to Paradise. Then their souls were taken back (by Allah), and they met together with the Lord of the worlds. He (Allah) said to this man who had striven hard in worship; Had you knowledge about Me or had you power over that which I had in My hand? He said to the man who sinned: Go and enter Paradise by My mercy. He said about the other: Take him to Hell. AbuHurayrah said: By Him in Whose hand my soul is, he spoke a word by which this world and the next world of his were destroyed.

The Prophet (ﷺ) said: There is no sin more fitted to have punishment meted out by Allah to its perpetrator in advance in this world along with what He stores up for him in the next world than oppression and severing ties of relationship.

The Prophet (ﷺ) said: Avoid envy, for envy devours good deeds just as fire devours fuel or (he said) "grass."

Sahl ibn AbuUmamah said that he and his father (AbuUmamah) visited Anas ibn Malik at Medina during the time (rule) of Umar ibn AbdulAziz when he (Anas ibn Malik) was the governor of Medina. He was praying a very short prayer as if it were the prayer of a traveller or near it. When he gave a greeting, my father said: May Allah have mercy on you! Tell me about this prayer: Is it obligatory or supererogatory? He said: It is obligatory; it is the prayer performed by the Messenger of Allah (ﷺ). I did not make a mistake except in one thing that I forgot. He said: The Messenger of Allah (ﷺ) used to say: Do not impose austerities on yourselves so that austerities will be imposed on you, for people have imposed austerities on themselves and Allah imposed austerities on them. Their survivors are to be found in cells and monasteries. (Then he quoted:) "Monasticism, they invented it; we did not prescribe it for them." Next day he went out in the morning and said: will you not go out for a ride, so that you may see something and take a lesson from it? He said: Yes. Then all of them rode away and reached a land whose inhabitants had perished, passed away and died. The roofs of the town had fallen in. He asked: Do you know this land? I said: Who acquainted me with it and its inhabitants? (Anas said:) This is the land of the people whom oppression and envy destroyed. Envy extinguishes the light of good deeds, and oppression confirms or falsifies it. The eye commits fornication, and the palm of the hand, the foot, body, tongue and private part of the body confirm it or deny it.

when a man cures anything, the curse goes up to heaven and the gates of heaven are locked against it. Then it comes down to the earth and its gates are locked against it. Then it goes right and left, and if it finds no place of entrance it returns to the thing which was cursed, and if it finds no place of entrance it returns to the thing which was cursed, and if it deserves what was said (it enters it), otherwise it returns to the one who uttered it. Abu Dawud said : Marwan b. Muhammad said: He is Rabah b. al-Walid who heard from him (nimran). He (Marwan b. Muhammad) said: Yahya b. Hussain was confused in it.

The Prophet (ﷺ) said: Do not invoke Allah's curse, Allah's anger, or Hell.

I heard the Messenger of Allah (May peace be upon him) say: Men given to cursing will not be witnesses or intercessors.

A man cursed the wind. The narrator Muslim's version has: The wind snatched away a man's cloak during the time of the Prophet (ﷺ) and he cursed it. The Prophet (ﷺ) said: Do not curse it, for it is under command, and if anyone curses a thing undeservedly, the curse returns upon him.

Something of her was stolen, and she began to curse him (i.e. the thief). The Messenger of Allah (ﷺ) said to her: Do not lessen his sin.

Do not hate each other; do not envy each other; do not desert each other; and be the servants of Allah as brethren. It is not allowed for a Muslim to keep apart from his brother for more than three days.

it is not allowable for a Muslim to keep apart from his brother for more than three days. When they meet, this turns away from him, and that turns away from him. The better of the two is the one who initiates in salutation.

The Prophet (ﷺ) said: It is not allowable for a believer to keep from a believer for more than three days. If three days pass, he should meet him and give him a salutation, and if he replies to it they will both have shared in the reward; but if he does not reply he will bear his sin (according to Ahmad's version) and the one who gives the salutation will have come forth from the sin of keeping apart.

The Messenger of Allah (ﷺ) said: It is not right for a Muslim to keep apart from another Muslim for more than three days. Then when he meets him and gives three salutations, receiving during that time no response, the other bears his sin.

The Prophet (ﷺ) said: It is not allowable for a Muslim to keep apart from his brother for more than three days, for one who does so and dies will enter Hell.

AbuKhirash heard the Messenger of Allah (ﷺ) say: If one keeps apart from his brother for a year, it is like shedding his blood.

The gates of Paradise are opened on Mondays and Thursdays, and forgiveness is granted to every man who does not associate anything with Allah, except for a man between whom and his brother there is rancor. Command will be given that they should be given respite till they conciliate. Abu Dawud said: The Prophet (ﷺ) kept apart from some of his wives for forty days, and Ibn 'Umar kept apart from his son till he died. Abu Dawud said: If keeping apart is meant for the sake of Allah, then it has no concern with it. 'Umar bin 'Abd al-'Aziz covered his face from a man.

Avoid suspicion for suspicion is the most lying form of talk. Do not be inquisitive about one another, or spy on one another.

The Prophet (ﷺ) said: The believer is the believer's mirror, and the believer is the believer's brother who guards him against loss and protects him when he is absent.
